| 1 | Particle size distribution in CPFD modeling of gas-solid flows in a CFB riser显示文摘A computational particle fluid dynamics(CPFD) numerical method to model gas-solid flows in a circulating fluidized bed(CFB) riser was used to assess the effects of particle size distribution(PSD) on solids distribution and flow.We investigated a binary PSD and a polydisperse PSD case.Our simulations were compared with measured solids concentrations and velocity profiles from experiments,as well as with a published Eulerian-Eulerian simulation.Overall flow patterns were similar for both simulation cases,as confirmed by experimental measurements.However,our fine-mesh CPFD simulations failed to predict a dense bottom region in the riser,as seen in other numerical studies.Above this bottom region,distributions of particle volume fraction and particle vertical velocity were consistent with our experiments,and the simulated average particle diameter decreased as a power function with riser height.Interactions between particles and walls also were successfully modeled,with accurate predictions for the lateral profiles of particle vertical velocity.It was easy to implement PSD into the CPFD numerical model,and it required fewer computational resources compared with other models,especially when particles with a polydisperse PSD were present in the heterogeneous flow. | Qinggong Wang Timo Niemi Juho Peltola Sirpa Kallio Hairui Yang Junfu Lu Lubin Weic | 2015 | Particuology2015，13，4： | 8 |
| 2 | CFD simulations of gas-solid flow in an industrial-scale circulating fluidized bed furnace using subgrid-scale drag models显示文摘Mesoscale flow structures such as clusters and streamers of particles are characteristic features of gas-solid flow in fluidized beds.Numerical simulations of gas-solid flows for industrial-scale fluidized beds are often performed using the Eulerian description of phases.An accurate prediction of this type of flow structure using the Eulerian modeling approach requires a sufficiently fine mesh resolution.Because of the long computational time required when using fine meshes,simulations of industrial-sized units are usually conducted using coarse meshes,which cannot resolve the mesoscale flow structures.This leads to an overestimation of the gas-solid drag force and a false prediction of the flow field.For these cases,a correction must be formulated for the gas-solid drag.We have simulated a large-scale circulating fluidized bed furnace using different gas-solid drag models and compared the model results with measurements. | Srujal Shah Kari My?h?nen Sirpa Kallio Timo Hypp?nen | 2015 | Particuology2015，13，1： | 4 |
| 3 | 受多氯联苯污染的淡水湖泊野生鱼类的组织病理学显示文摘本研究的目的是利用组织病理学作为终点,来评估野生鱼类长期暴露于多氯联苯(PCBs)非致死浓度时潜在的中毒影响。生活在多氟联苯污染的淡水湖泊中的欧鳊(Abramis brama)和赤梢鱼(Aspius aspius)的组织病理学研究揭示了两种鱼的肾小球细胞的异常细胞改变。肾小球毛细管扩张症(DGC)、肾小球膜水肿(ME)、鲍曼管即肾小球囊内脏层和腔壁层之间的粘连(ABC)和鲍曼管空间的充塞(FBS)是湖鱼的高度流行特征。在参考点捕到的鱼中,每种损伤的发生率很低,或者说几乎没有见到这类损伤。肝、鳃、生殖腺、脾和肠的细胞变化均与季节变化有关。研究结果表明,所观察到的肾小球体有一些有组织病理改变,特别是肾小球毛细管扩张症和肾小球膜水肿,这可能表明是由多氯联苯和相关化合物引起的长期化学应激反应造成的,也可能是长期暴露于多氯联苯从而抑制和减弱了鱼的免疫系统,使它们易遭继发性寄生虫的感染。 | Kari Koponen Mark S.Myers Ossi Ritola Sirpa E.Huuskonen Pirjo Lindstrm-Sepp 李康民 | 2001 | AMBIO-人类环境杂志2001，30，3： | 2 |
