| 1 | Unravelling the complexity in achieving the 17 sustainable-development goals显示文摘It is now more than 3 years since the ratification of the 2030 Agenda for Sustainable Development framework[1]but,according to the latest progress report,unless the rate of progress increases,it is challenging that all of the Sustainable Development Goals(SDGs)will be achieved by 2030[2].With only 11 years remaining until the 2030 deadline,it has become imperative to develop a plan of action to enable the full agenda to be realized.Specifically,there is an urgent need for a holistic approach to clarify the interrelationships between the 17 SDGs,while also taking into account their complexity and their sometimes mutually reinforcing or conflicting nature.Trying to achieve these goals separately in succession is nonsensical,but pursuing them simultaneously is impractical[3]. | Bojie Fu Shuai Wang Junze Zhang Zengqian Hou Jinghai Li | 2019 | National Science Review2019，6，3： | 32 |
| 2 | Virtual experimentation through 3D full-loop simulation of a circulating fluidized bed显示文摘Eulerian granular multiphase model with a drag coefficient correction based on the energy-minimization multi-scale (EMMS) model was used to simulate a semi-industry scale circulating fluidized bed (CFB). Three-dimensional (3D), time-dependent simulation of a full-loop CFB revealed that the axial profiles of cross-sectionally averaged solid volume fraction, and the radial profiles of solid axial velocity and solid volume fraction were in reasonable agreement with experimental data. Based on this agreement, database derived from experiments not yet accomplished was replenished with such simulations, and fluid regime diagrams and pressure balance around the CFB loop were derived accordingly. This work presents an integrated viewpoint on CFB and unfolds a fresh paradigm for CFB modeling, which can be expected to help resolve certain issues long in dispute but hard for experiments. | Nan Zhang Bona Lu Wei Wang Jinghai Li | 2008 | Particuology2008，6，6： | 23 |

| 4 | Focusing on the meso-scales of multi-scale phenomena-In search for a new paradigm in chemical engineering显示文摘To celebrate the 90th birthday of Professor Mooson Kwauk,who supervised the multi-scale research at this Institute in the last three decades,we dedicate this paper outlining our thoughts on this subject accumulated from our previous studies.In the process of developing,improving and extending the energyminimization multi-scale(EMMS)method,we have gradually recognized that meso-scales are critical to the understanding of the different kinds of multi-scale structures and systems.It is a common challenge not only for chemical engineering but also for almost all disciplines of science and engineering,due to its importance in bridging micro-and macro-behaviors and in displaying complexity and diversity.It is believed that there may exist a common law behind meso-scales of different problems,possibly even in different fields.Therefore,a breakthrough in the understanding of meso-scales will help materialize a revolutionary progress,with respect to modeling,computation and application. | Jinghai Li Wei Ge Wei Wang Ning Yang | 2010 | Particuology2010，8，6： | 16 |
| 5 | Quasi-real-time simulation of rotating drum using discrete element method with parallel GPU computing显示文摘Real-time simulation of industrial equipment is a huge challenge nowadays. The high performance and fine-grained parallel computing provided by graphics processing units (GPUs) bring us closer to our goals. In this article, an industrial-scale rotating drum is simulated using simplified discrete element method (DEM) without consideration of the tangential components of contact force and particle rotation. A single GPU is used first to simulate a small model system with about 8000 particles in realtime, and the simulation is then scaled up to industrial scale using more than 200 GPUs in a 1D domain-decomposition parallelization mode. The overall speed is about 1/11 of the real-time. Optimization of the communication part of the parallel GPU codes can speed up the simulation further, indicating that such real-time simulations have not only methodological but also industrial implications in the near future. | Ji Xu Huabiao Oi Xiaojian Fang Liqiang Lu Wei Ge Xiaowei Wang Ming xu Feiguo Chen xianfeng He Jinghai Li | 2011 | Particuology2011，9，4： | 16 |
| 6 | Macro-scale pseudo-particle modeling for particle-fluid systems显示文摘Pseudo-particle modeling (PPM) is a particle method (PM) proposed in 1996. Though it is effective for the simulation of microscopic particle-fluid systems, its application to practical systems is still limited by computational cost. In this note, we speed up the computation by using a combination of weighted averaging with finite difference techniques to upgrade the particle interactions to a fluid element level, which conforms to the Navier-Stokes equation. The approach, abbreviated to MaPPM, is then applied to the problem of one-dimensional Poiseuille flow with a quantitative comparison to the results of another related PM--smoothed particle hydrodynamics (SPH), where the accuracy and efficiency of MaPPM is found to be much better than that of SPH. Flows around a cylinder and multiple freely moving particles are also simulated with the new model, resulting in reasonable flow pattern and drag coefficient. The convergence and robustness of the algorithm prove promising. | Wei Ge Jinghai Li | 2001 | Chinese Science Bulletin2001，46，18： | 12 |
| 7 | Pseudo-particle simulation of multi-scale heterogeneity in fluidization显示文摘Fluidization is a process of wide application, but its dynamic behavior is not well understood because of its multi-scale heterogeneity and regime multiplicity which are difficult to simulate in traditional numerical methods. By discretizing the fluid phase into a large number of interactive simple particles, which can incorporate many-body moving boundaries easily, pseudo-particle modeling (PPM) has re-produced reasonable radial and axial heterogeneity on macro-scale as well as solids clustering and fluid flows on meso- and micro-scales. The simulation suggests a consistent evolution of the complexity across different scales with itself serving as an ideal exploring tool. | GE Wei, ZHANG Jiayuan, LI Tinghua & LI Jinghai Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100080, China | 2003 | Chinese Science Bulletin2003，48，7： | 11 |
| 8 | Commissioning progress of the FAST显示文摘The Five-hundred-meter Aperture Spherical radio Telescope(FAST) was completed with its main structure installed on September 25, 2016, after which it entered the commissioning phase. This paper aims to introduce the commissioning progress of the FAST over the past two years. To improve its operational reliability and ensure effective observation time, FAST has been equipped with a real-time information system for the active reflector system and hierarchical commissioning scheme for the feed support system, which ultimately achieves safe operation of the two systems. For meeting the high-performance indices, a highprecision measurement system was set up based on the effective control methods that were implemented for the active reflector system and feed support system. Since the commissioning of the FAST, a low-frequency ultra-wideband receiver and 19-beam1.05-1.45 GHz receiver have been mainly used. Telescope efficiency, pointing accuracy, and system noise temperature were completely tested and ultimately achieved the acceptance indices of the telescope. The FAST has been in the process of national acceptance preparations and has begun to search for pulsars. In the future, it will still strive to improve its capabilities and expand its application prospects. | Peng Jiang YouLing Yue HengQian Gan Rui Yao Hui Li GaoFeng Pan JingHai Sun DongJun Yu HongFei Liu NingYu Tang Lei Qian JiGuang Lu Jun Yan Bo Peng ShuXin Zhang QiMing Wang Qi Li Di Li | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，5： | 11 |
| 9 | Paradigm shift in science with tackling global challenges显示文摘In recent years,the paradigm shift in science has become a hot topic in the global scientific community.Scientific problems unsolved with existing knowledge or through traditional approaches can be found in all disciplines.On the other hand,more effective ways to meet global challenges,such as climate change,major diseases,natural disasters,and governance of social and economic systems,are still to be explored.Unfortunately it remains paralleled discussion on these two aspects,with the former involving a more generic view of the science developm ent trend-the paradigm shift,while the latter concerning specific real-world problems to be solved. | Jinghai Li Wenlai Huang | 2019 | National Science Review2019，6，6： | 9 |
| 10 | Molecular dynamics simulation of complex multiphase flow on a computer cluster with GPUs显示文摘Compute Unified Device Architecture (CUDA) was used to design and implement molecular dynamics (MD) simulations on graphics processing units (GPU). With an NVIDIA Tesla C870, a 20-60 fold speedup over that of one core of the Intel Xeon 5430 CPU was achieved, reaching up to 150 Gflops. MD simulation of cavity flow and particle-bubble interaction in liquid was implemented on multiple GPUs using a message passing interface (MPI). Up to 200 GPUs were tested on a special network topology, which achieves good scalability. The capability of GPU clusters for large-scale molecular dynamics simulation of meso-scale flow behavior was, therefore, uncovered. | CHEN FeiGuo GE Wei LI JingHai | 2009 | Science China Chemistry2009，52，3： | 9 |
| 11 | Mesoscience: exploring the common principle at mesoscales显示文摘BACKGROUND OF THE EMERGING MESOSCIENCE In studying a complex system in science,engineering or society,we usually observe its macroscale(system-scale)behavior first,then go deep into mechanisms at the microscale(unit-scale)and finally try to correlate these two scales to reach a complete understanding.However,it is increasingly recognized that correlating these two scales is quite difficult,and some common principles are inevitably missing in between these two extrema[1,2]. | Wenlai Huang Jinghai Li Peter P.Edwards | 2018 | National Science Review2018，5，3： | 9 |

| 13 | General approach for discrete simulation of complex systems显示文摘By applying a general algorithm to different particle models, i.e. molecular dynamic (MD) and macro-scale pseudo-particle models (MaPPM), two physical phenomena of distinct nature and scale differences, i.e. the mutual diffusion of two gases and the instability on the interface between two fluids, are simulated successfully. It demonstrates the possibility that the general algorithms of good parallelism and software of modular architecture can be established for complex physical systems based on the particle methods (PMs), which will thereby develop into a mainstream approach as finite element (FE) and finite difference (FD) approaches. | Wei Ge Jinghai Li | 2002 | Chinese Science Bulletin2002，47，14： | 7 |
| 14 | Parallelizing of macro-scale pseudo-particle modeling for particle-fluid systems显示文摘A parallel algorithm suitable for simulating multi-sized particle systems and multi- phase fluid systems is proposed based on macro-scale pseudo-particle modeling (MaPPM). The algorithm employs space-decomposition of the computational load among the processing ele- ments (PEs) and multi-level cell-subdivision technique for particle indexing. In this algorithm, a 2D gas-solid system is simulated with the temporal variations of drags on solids, inter-phase slip velocities and solids concentration elaborately monitored. Analysis of the results shows that the algorithm is of good parallel efficiency and scalability, demonstrating the unique advantage of MaPPM in simulating complex flows. | TANG Dexiang GE Wei WANG Xiaowei MA Jingsen GUO Li LI Jinghai | 2004 | Science China Chemistry2004，47，5： | 6 |

| 16 | Complexity at Mesoscales:A Common Challenge in Developing Artificial Intelligence显示文摘Exploring the physical mechanisms of complex systems and making effective use of them are the keys to dealing with the complexity of the world.The emergence of big data and the enhancement of computing power,in conjunction with the improvement of optimization algorithms,are leading to the development of artificial intelligence(AI)driven by deep learning.However,deep learning fails to reveal the underlying logic and physical connotations of the problems being solved.Mesoscience provides a concept to understand the mechanism of the spatiotemporal multiscale structure of complex systems,and its capability for analyzing complex problems has been validated in different fields.This paper proposes a research paradigm for AI,which introduces the analytical principles of mesoscience into the design of deep learning models.This is done to address the fundamental problem of deep learning models detaching the physical prototype from the problem being solved;the purpose is to promote the sustainable development of AI. | Li Guo Jun Wu Jinghai Li | 2019 | Engineering2019，5，5： | 5 |
| 17 | Application of the Mole-8.5 supercomputer:Probing the whole influenza virion at the atomic level显示文摘Discrete computer simulations are quite helpful in understanding dynamic structures in complex systems.Recently,using the Mole-8.5 supercomputer and molecular dynamics simulations as a'computational microscope',we simulated the dynamic structure of a whole H1N1 influenza virion in solution for the first time at the atomic level.In total,300 million atoms in a periodic cube with an edge length of 148.5 nm were simulated.Using 288 low level hybrids with 1728 C2050 GPUs and a software package developed specifically for the hardware,the simulation executed 770 ps/d with an integration time step of 1 fs,and analyzed the dynamic structure.With the tremendous computational power of GPUs,efficient software packages for various hardware designs,and consistent physical models,more challenging applications will be carried out in the near future. | XU Ji WANG XiaoWei HE XianFeng REN Ying GE Wei LI JingHai | 2011 | Chinese Science Bulletin2011，56，20： | 5 |

| 19 | Extending EMMS-based models to CFB boiler applications显示文摘Recently,EMMS-based models are being widely applied in simulations of high-throughput circulating fluidized beds(CFBs) with fine particles.Its use for low flux systems,such as CFB boiler(CFBB),still remains unexplored.In this work,it has been found that the original definition of cluster diameter in EMMS model is unsuitable for simulations of the CFB boiler with low solids flux.To remedy this,we propose a new model of cluster diameter.The EMMS-based drag model(EMMS/matrix model) with this revised cluster definition is validated through the computational fluid dynamics(CFD) simulation of a CFB boiler. | Bona Lu Nan Zhang Wei Wang Jinghai Li | 2012 | Particuology2012，10，6： | 4 |
| 20 | Numerical investigation of granular flow similarity in rotating drums显示文摘The theory of flow similarity has not been well established for granular flows,in contrast to the case for conventional fluids,owing to a lack of reliable and general constitutive laws for their continuum description.A rigorous investigation of the similarity of velocity fields in different granular systems would be valuable to theoretical studies.However,experimental measurements face technological and physical problems.Numerical simulations that employ the discrete element method(DEM) may be an alternative to experiments by providing similar results,where quantitative analysis could be implemented with virtually no limitation.In this study,the similarity of velocity fields is investigated for the rolling regime of rotating drums by conducting simulations based on the DEM and using graphics processing units.For a constant Froude number,it is found that the particle-to-drum size ratio plays a dominant role in the determination of the velocity field,while the velocity field is much more sensitive to some material properties than to others.The implications of these findings are discussed in terms of establishing theoretical similarity laws for granular flows. | Huabiao Qi Ji Xu Guangzheng Zhou Feiguo Chen Wei Ge Jinghai Li | 2015 | Particuology2015，13，5： | 4 |
