CFD simulation of Dynamic Filtration system with Rotating Discs

摘要：

A three-dimensional (3D) computational fluid dynamics (CFD) simulation was implemented to investigate the hydrodynamics situation of a dynamic filtration system. The flow patterns were visualized by the simulation. The simulation result shows that high shear stresses on the rotating disc and the stationary membrane surface can be obtained at different rotating speeds. The shear stress steps up rapidly according to the speed of 500 rpm to 2500 rpm. Excellent agreement was found between the simulation results and the analytic solution results calculated by the references. The simulant value of discs force moment was used to calculated the mechanical power of the disc. The effective power raised from about 7 w to 85 w as the rotating speed increase.
