基于SPH方法的凝胶推进剂一次雾化仿真研究
Simulation research on first atomization characteristics of gelled propellant based on SPH method
摘要
Abstract
As the free surface and large deformation problem in first atomization were both challenges to traditional grid based method,the first atomization characteristics of gelled propellant using Smoothed Particle Hydrodynamics (SPH) method was investigated. The computational models were simplified from the doublet like-on-like impinging jet injector. The particle number of each computational model was controlled at level of 105. As the shear rate during the impinging process was high,gelled propellant was treated as high viscous Newtonian fluid. The influences of velocity, impinging angle and viscosity were investigated. The simulation results show an agreement with analysis and experiment, which proves that SPH is an efficient method to solve the first atomization problem.关键词
