Abstract

In raining days, the water drops can enter the compressor and cause security problems. However, there is still no appropriate numerical method for simulating the interaction between water drops and solid wall. The Euler-Lagrange (EL) method is usually regarded as the best solution for this problem, but it considers each water drop as a fluid particle and cannot allow the simulation of deformation. We propose to combine the Smoothed Particle Hydrodynamics (SPH) method with the EL method, which is named as SPH-EL method. In this contribution we introduce the idea of SPH-EL method as well as two key techniques: tracking the particle deformation and regrouping the distorted particles. Finally we present a 2D simulation with SPH method and will apply the SPH-EL method to improve the simulation in the future.
