| 2 | Optimization of Baffled Rectangular and Prismatic Storage Tank Against the Sloshing Phenomenon显示文摘The fluid motion in partially filled tanks with internal baffles has wide engineering applications. The installation of baffles is expected to reduce the effect of sloshing as well as the consequent environmental damages. In the present study, a series of experimental tests are performed to investigate the sloshing phenomenon in a baffled rectangular storage tank. In addition, the sloshing phenomenon is also modeled by using Open Foam. Based on the experimental and numerical studies, optimization of the geometric parameters of the tank is performed based on some criteria such as tank area, entropy generation, and the horizontal force exerted on the tank area due to the sloshing phenomenon.The optimization is also carried out based on the entropy generation minimization analysis. It is noted that the optimum baffle height is in the range of h_b/h_w=0.5-0.75 in the present study(where h_b and h_w are the baffle height and water depth, respectively). Based on the results, the optimal design of the tank is achieved with R_A= 0.9-1.0(where R_A=L/W, L and W are the length and width of the tank, respectively). The results also show that the increase of h_b can lead to a decrease of the maximum pressure and horizontal force exerted on the tank. It is also noted that the horizontal force exerted on the tank firstly continues to increase as the sway motion amplitude increases.However, as the normalized motion amplitude parameter, a/L(The parameter a is the motion amplitude), exceeds0.067, the effect of motion amplitude on the force is not obvious. The same optimization is also performed in the multiple-variable-baffled tank and prismatic storage tank. | Hassan SAGHI NING De-zhi CONG Pei-wen ZHAO Ming | 2020 | China Ocean Engineering2020，34，5： | 3 |
| 3 | A New Arrangement with Nonlinear Sidewalls for Tanker Ship Storage Panels显示文摘Sloshing phenomenon in a moving container is a complicated free surface flow problem. It has a wide range of engineering applications, especially in tanker ships and Liquefied Natural Gas (LNG) carriers. When the tank in these vehicles is partially filled, it is essential to be able to evaluate the fluid dynamic loads on tank perimeter. Different geometric shapes such as rectangular, cylindrical, elliptical, spherical and circular conical have been suggested for ship storage tanks by previous researchers. In this paper a numerical model is developed based on incompressible and inviscid fluid motion for the liquid sloshing phenomenon. The coupled BEM-FEM is used to solve the governing equations and nonlinear free surface boundary conditions. The results are validated for rectangular container using data obtained for a horizontal periodic sway motion. Using the results of this model a new arrangement of trapezoidal shapes with quadratic sidewalls is suggested for tanker ship storage panels. The suggested geometric shape not only has a maximum surrounded tank volume to the constant available volume, but also reduces the sloshing effects more efficiently than the existing geometric shapes. | M.

| 10 | 双隔板矩形液舱内抑制晃荡的优化研究显示文摘A dual-baffled rectangular tank with different configurations is proposed to reduce the sloshing effect,and design optimization is conducted through numerical simulations with open-source software,namely OpenFOAM,based on the computational fluid dynamic model.A series of physical experiments in the dual-baffled rectangular tank is performed for model validation and design optimization with the measured water surface elevation distributions along the tank.The optimization uses the calculated maximum horizontal force exerted on the tank and entropy generation(EG)as the criterion.Results show that the dual-baffle configuration positioned at the tank center is more effective in reducing the sloshing than that of the single baffle when the relative baffle height and initial water depth ratio(Hb/Hw,where Hb and Hw represent baffle height and static water depth,respectively)are larger than 0.5.However,such an effect then diminishes when the ratio is larger than 0.75.The effect of the dual-baffle configuration on the sway motion under the condition of different motion amplitudes and frequencies is also evaluated.The results show that the reduction in the maximum horizontal force is almost the same for dual-and single-baffled configurations and reaches the minimum when the sway motion amplitude is near 0.03 m.The dual-baffled configuration for the angular frequency of the sway motion is more effective than the single-baffled in reducing the sloshing at the low angular frequencies but is only less effective at high angular frequencies.Furthermore,the optimal baffle inclination angle is 85°when the inclined straight and curved baffles are used,and curved baffles can successfully decrease the horizontal force exerted on the tank and EG. | Hassan Saghi 宁德志 潘顺琪 Reza Saghi | 2022 | Journal of Marine Science and Application2022，21，1： | 1 |

| 19 | Microstructural abnormalities are evident by histology but not HR-pQCT at the periosteal cortex of the human tibia under CVD and T2D conditions显示文摘Cortical bone microstructure deficits may increase fracture risk in individuals with cardiovascular disease and diabetes.High resolution peripheral quantitative computed tomography(HR-pQCT)enables in vivo microstructure characterization but is limited in its ability to visualize important biological features.We conducted histological analyses and HR-pQCT imaging of distal tibia bone samples from 6 donors with cardiovascular disease(CVD)and type 2 diabetes mellitus(T2D).Histology but not HR-pQCT identified previously undocumented morphopathological deficits that may contribute to cortical bone fragility.These observations may provide guidance for improved HR-pQCT microstructural characterization as well as insight into mechanisms of cortical bone degradation. | Barbara Garita Jenna Maligro Saghi Sadoughi Po Hung Wu Ellen Liebenberg Andrew Horvai Thomas M.Link Galateia J.Kazakia | 2021 | Medicine in Novel Technology and Devices2021，，2： | 0 |
| 20 | Numerical simulation of sediment deposition and trapping efficiency estimation in settling basins,considering secondary flows显示文摘In this paper,sediment deposition and trapping efficiency in shallow rectangular reservoirs were numerically estimated considering secondary flows.In order to do this,three dimensional(3D) steady,incompressible,Reynolds-averaged Navier-Stokes(RANS) equations with the standard κ-ε turbulence model were used as the governing equations.The drift-flux model also was used to model the solid phase.In the next step,the developed model was validated using the available data.Then it was used to simulate the sediment deposition and trapping efficiency in shallow rectangular reservoirs,considering secondary flows.The results show the sediment is trapped in the inlet corner of the reservoir,and two pairs of large vortices on the sides and two pairs of small vortices at the inlet corner of the reservoir are observed.Finally,the effects of the input angle of the reservoir to the trapping efficiency are evaluated and the results are discussed. | Esmail Lakzian Hassan Saghi Omid Kooshki | 2020 | International Journal of Sediment Research2020，35，4： | 0 |
