采用CARS试验技术与UFPV数值方法研究航空发动机燃烧室
Experimental and simulation study of aeroengine combustor based on CARS technology and UFPV approach
摘要
Abstract
Based on the Unsteady Reynolds Averaged Navier Stokes (URANS)method,a three-dimensional two-phase turbulent combustion numerical software for aeroengine combustor has been developed.The physical and chemical processes taking place in the liquid fuel are simu-lated completely,including liquid film formation,breakup,evaporation and combustion.LISA and KH-RT are used as the primary and second atomization model respectively,and also the standard evaporation model is used to simulate the evaporation process.Besides,detailed chemical mechanism of kerosene is used for reaction kinetics,and the Unsteady Flamelet/Progress Variable (UFPV)approach in which the unstable combustion characteristics of the flame could be simula-ted is used as the combustion model.The temperature and species of the flow field and the diam-eter of fuel droplets in the aeroengine combustor are obtained.At the same time,the Coherent Anti-stokes Raman Scattering (CARS)technology is used to measure the temperature in the pri-mary zone of the aeroengine combustor.Then the temperature of the simulation is compared with that measured by CARS technology,and the calculation error of numerical results is less than 7.3%.The studies have shown that the numerical method in this paper and UFPV approach can simulate the two-phase turbulent combustion process appropriately in the aeroengine combustor.关键词
