摘要
采用耦合求解的方法进行了冲压发动机进气道/燃烧室/尾喷管流场一体化计算,进气道采用单一气体、变比热比模型,燃烧室和尾喷管采用多组分化学动力学模型,湍流模型为k-g湍流模型。进气道与燃烧室界面通过流量、静压等参数实现耦合。结果表明,通过合理设计参数的传递方式,可以快速实现进气道/燃烧室/尾喷管流场的耦合求解,流场分布合理。
An efficient multi-code CFD solver was designed to simulate the integrated flowfields in a ramjet engine in a loosely coupled manner. The muhiblock, multigrid, single-species, turbulence flow solver was used to simulate the flows in the inlet, while a multi-species one to simulate the flows in the combustor and nozzle. The k-g turbulence model was used in the calculations. By means of carefully designed message feedback of mass flow rate, static pressure, etc. , on the inlet-combustor interface, the flowfield of inlet and combustor can be solved efficiently. The turbulent flowfields obtained are reasonable.
