• A numerical scheme is proposed for the direct simulation of complex solid-liquid-gas three-phase flows. coupled LBM-DEM model ensuring mass conservation proposed. The upward migration bubbles through a brine-filled sediment column successfully simulated at various conditions. Simulation results indicate three different flow regimes: connected finger flow, transition and dispersed bubbly flow....

Abstract At present, in the aspect of numerical simulation a cycloid pump, most researchers are based on CFD (computational fluid dynamics) to analyze pump under different operating conditions (such as speed, temperature), and performance FSI (fluid solid interactions) is rare. Firstly, model cycloidal established COMSOL. The results obtained by applying verified experiments. Then, flow rotatin...
