【摘要】:隨著計(jì)算機(jī)、計(jì)算機(jī)輔助制造等技術(shù)的發(fā)展,數(shù)值模擬逐漸成為航空發(fā)動(dòng)機(jī)設(shè)計(jì)手段之一。航空發(fā)動(dòng)機(jī)燃燒室內(nèi)是復(fù)雜的兩相湍流燃燒過程,為了準(zhǔn)確模擬這一過程,高精度兩相湍流燃燒模型組成為航空發(fā)動(dòng)機(jī)燃燒室設(shè)計(jì)師必要的工具。本文從兩相湍流數(shù)值模擬角度出發(fā),對概率密度函數(shù)輸運(yùn)方程模型、火焰面模型和二階矩模型這3種常用的燃燒模型的發(fā)展現(xiàn)狀進(jìn)行簡要綜述。
[Abstract]:With the development of computer, computer aided manufacturing and other technologies, numerical simulation has become one of the means of aeroengine design. The aero-engine combustion chamber is a complicated two-phase turbulent combustion process. In order to simulate the process accurately, the high-precision two-phase turbulent combustion model is a necessary tool for the designer of the aero-engine combustion chamber. In this paper, from the point of view of numerical simulation of two-phase turbulence, the development status of three commonly used combustion models, namely, probability density function transport equation model, flame surface model and second-order moment model, is briefly reviewed.
