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...
Three-dimensional numerical simulation and analysis of the complicated unsteady compressible turbulence flow field in a large-scale gas control valve are performed, using computational fluid dynamics method. Flow visualization of three-dimensional flow field at different valve opening is presented. The velocity distribution and pressure loss of gas flow are studied. The flow behavior of eddy current...
Based on computational fluid dynamic (CFD) method, flow field analysis and structural optimization of a three-phase hydrocyclone were carried out by using FLUENT soft pack. By numerical simulation analysis on de-gas and de-sand functions of the three-phase hydrocyclone, effect of different geometric parameters on de-gas and de-sand functions is studied. It is found that the change of overflow tube...
A two-fluid model was adopted to simulate the three-dimensional gas-liquid flow in an aeration tank. During the modeling, different process parameters of aeration tank was simulated, and the gas-liquid flow behavior in aeration tank was analyzed. The CFD simulation and PIV measurement were both used to analyze the flow field in the aeration tank. The result shows that with the increasing of the depth,...
Smooth Particle Hydrodynamics (SPH) is an accurate method in fluid numerical simulation. In this paper we introduce a calculating algorithm based on the SPH, and propose an interactive method to simulate fluids with free surfaces. This method is completely consistent with the dynamic behavior of a viscous fluid, namely described by Navier-Stokes equations. In addition, for online simulation, we adopt...
