高速飞行器液膜冷却的自适应分辨率光滑粒子法模拟研究
Numerical study of liquid film cooling using smoothed particle hydrodynamics with adaptive spatial resolution
摘要
Abstract
Hypersonic vehicles demand advanced thermal protection due to extreme Mach numbers,prolonged flight,and high loads.Liquid film cooling,with advantages like evaporative phase change and high specific heat capacity,shows great potential for active thermal protection in hypersonic vehicles.However,related research remains insufficient,with experimental studies facing multiple limitations while conventional numerical methods cannot simultaneously handle complex issues such as large density ratio gas-liquid interfaces,liquid evaporation/boiling,and fluid-structure interactions.This paper develops a smoothed particle method combining the adaptive resolution algorithm with multiphase heat and the mass transfer algorithm.The adaptive resolution SPH method is validated through two typical cases of Poiseuille flow and Kelvin-Helmholtz instability,followed by analysis of key factors affecting the liquid film cooling process.关键词
