| 摘 要： | 针对发动机燃烧室由于高温升和低污染而使可用冷却空气大量减少的技术难题,设计了一套切向进气发散小孔的单管燃烧室模型.使用热流固耦合方法,通过对Navier-Stokes(N-S)方程的求解,对其流场特性和火焰筒壁温进行了数值模拟研究.计算在三维坐标系下,采用拉格朗日法计算燃油颗粒的轨迹,非预混模型计算燃烧,离散坐标模型计...

| Abstract: | To solve technical difficulties resulting from high temperature rise and low emission of new generation engine combustor,a single tube combustor model with tangential effusion cooling technology was designed.Numerical simulation was conducted to study the flow field characteristics and wall temperature distribution of combustor liner by solving Navier-Stokes(N-S) equations with thermal fluid-solid coupling method.The liner wall temperature distribution was computed under two conditions by three-dimensional ... |
