WebJan 30, 2024 · 4. Conclusions. In this work, inspired by the PS-LBM, we proposed a diffuse-interface lattice Boltzmann method for fluid–particle interaction problems. The distinct … WebDiscontinuous flow features are captured using a diffuse interface method. A distinguishing characteristic of the method is the proper treatment of the interface zone as a mixing region of liquid and gas. The governing equations are discretized by a Godunov-type finite volume method with explicit time stepping using a low-storage Runge-Kutta ...
