摘要
以HIFiRE-2超燃冲压发动机为研究对象,针对高马赫数超燃模态,通过与试验结果对比,考察了涡耗散模型的工程应用能力,同时研究了湍流模型、湍流施密特数和可压缩修正对流场的影响,结果表明:涡耗散模型适用于超燃冲压发动机工程算例的仿真;BSL κ-ω湍流模型,湍流施密特数为0.4,可压缩性修正开启,在高马赫数超燃模态时能够取得较好的计算结果。
Taking HIFiRE-2 Scramjet as the research object,the engineering capability of eddy dissipation model is investigated by comparing with experiment at high mach case and the influence of turbulence model,Schmidt number,and compressibility correction are studied.The results show that eddy dissipation model is applicable to simulation of scramjet.BSL κ-ω and turning on compressibility correction can obtain the best result when Schmidt number is 0.4.
