Numerical simulation of the solidification of a single molten droplet impinging on flat plate using multi-resolution MPS method

Abstract

Particle deposition in a jet engine is a complex physical phenomenon that includes free-surface flow and phase changes. The moving particle simulation (MPS) method is extremely useful for numerical simulations, although it incurs high computational costs. In this study, we used the multiresolution MPS (MRMPS) method to simulate the deposition phenomenon of a liquid droplet to reduce the computational cost. When using the MRMPS method, we modified some conditions concerning the division of the computational particle. As a result, the spreading behavior and rim shape of a droplet impinging on a cold wall with solidification showed reasonable agreement with the experiment. In addition, this model has the advantage of reducing the computational time.
