In modern times, computer technology is used in various fields in the world. In this paper, CFD(computational fluid dynamics) was applied to build mathematical model to simulate continuous and dispersed multiphase flow in the experimental systems and an industrial electrolyzer. The Volume of Fluid model was used in the mathematical model for multi-phases. Cold model system of complex multiphase behavior...
Based on the Navier-Stokes equations for viscous, incompressible fluid and VOF method, the numerical experiment platform of oil containment by rigid floating boom in wave is established, utilizing the commercial CFD software FLUENT, and the waves are generated by defining the velocity of water particle on the inlet boundary. The volume of fluid (VOF) model is used to distinguish the three immiscible...
In this paper, the turbulent flow over a triple forward facing step configuration was investigated numerically. To that end, numerical simulations are performed for 4 Re numbers and 36 different geometries. Turbulence is modeled in all simulations using the Standard k-?? model. The resulting flow field is examined in terms of pressure coefficient, vorticity and turbulent kinetic energy. Furthermore,...
The flow field of hydrocyclone was simulated using commercial software FLUENT and Reynolds stress model in the paper. The results show that it correctly predicts the distribution rules of the velocity and the characteristics of Rankine-eddy. The simulation results are in good agreement with the experimental data published before, which proves the validity of mathematical model and computation method...
Numerical simulation of two-dimensional stagnation-point flow is investigated with the computational fluid dynamics (CFD) software of STAR-CD and results are compared with those obtained from the similarity solution. Study shows that velocity profiles are in good agreement between numerical simulation and similarity solution for high aspect ratio in the stagnation-point region. Numerical simulation...
