Study on Hydromechanics with Particles and Bubbles Based on Finite Element Modeling

Abstract The hydromechanics with foams and particles has important scientific and commercial significance. The presence of solid particles will greatly change the behavior of the multiphase/multicomponent flow in the bubble, which is a scientific issue unexplored. So this article simulates the foam layer and platform edge and the hydrodynamic laws of particles along the interface and inside the film were studied. As a result, the explicit analytical expressions for the drag coefficient and torque coefficient of spherical particles attached to a flat stress-free interface between two immiscible fluids are constructed by using the finite element method based on computational fluid dynamics (CFD) under the condition of low Reynolds number. The hydrodynamic data of the translational sphere and the rotating sphere under different motion states are analyzed respectively, and the flow mechanics law of the foam bridging region is analyzed.
