发展了一种低涵道比混合排气加力涡轮风扇发动机接通加力时的数值模拟方法。该方法考虑混合室加力燃烧室、主燃烧室和外涵道的容积效应
风扇、压气机、高压和低压涡轮等部件的特性
加力燃烧室供油管的充油时间。以混合室加力燃烧室、主燃烧室和外涵道3个容积室的动态方程为基础
用很小的时间步长逐渐逼近
计算不需要迭代
速度快
精度满足工程要求。
Numerical simulation of turbofan engine afterburner light-on process was presented.The volume effects of mixer
afterburner and outlet duct was taken into account.Performances of fan
compressor
turbine and time consumed for filling afterburner fuel ducts were incorporated into simulation.Based on the dynamic equations of three volumes
i.e.volumes of afterburner
main combustion chamber and fan duct
the simulation could be rapidly performed with high fidelity and without iteration.
