Examples
- In arbitrary curvilinear coordinates , the wall function is used for treating near wall regions . the influences of two different inlet gas parameter distributions and turbulent combustion models , as well as three different afterburners on turbulent combustion flow fields and wall temperature profiles are calculated . comparisons of experiment results and calculations results show that second - moment combustion model is reasonable for modeling turbulent reacting flows , inlet gas parameter distributions is more important . calculation method is reliable and can be used for the optimum design of afterburner
数值研究三种不同几何形状、两种进口气流参数分布、两种紊流燃烧模型等对加力室内各气流参数、隔热屏和加力室筒体壁面温度分布的影响,计算结果与试验数据比较表明:不同几何形状加力室对加力室内紊流燃烧流场的影响要比进口气流参数分布大些,正确给定进口气流参数分布较为重要,二阶矩紊流燃烧模型更适用摸拟三维紊流燃烧流动,计算方法合理,编制的计算程序可靠,可供加力燃烧室优化设计用。 - In arbitrary curvilinear coordinate systems , three dimensional turbulent combustion flow fields of the three kinds of turbofan engine afterburner with the longitudinal heat shield 、 outer cold flow and the jet nozzle are simulated . the three - dimensional body - fitted grids are generated by an elliptical grid generation procedure and zone method
