Speech Title: Two kinds of meshless method for the numerical simulation of multiphase flow with application in bio-medical engineering

Abstract

Meshless methods have great potential for the numerical simulation of multiphase flow due to their Lagrangian nature, among which vortex method and moving particle semi-implicit (MPS) method are promising. In the vortex method, the flow field of the continuous phase is solved by the discretization of vorticity equation, and the bubble/droplet/particle equation is introduced to simulate the motion of discrete phase. In the MPS method, fluids are discretized into different particles, and all the operators in the N-S equations are solved by the interaction of these particles. After improvement of stability, MPS has great advantages in the simulation of multiphase flow with deformable interface, because interface tracking/capturing techniques are not necessary. In this work, these two methods are developed to respectively simulate the cryogen spray cooling and laser-induced thrombus formation, thereby improve the therapy effect of laser treatment of vascular dermatosis.
