摘要
从雷诺平均的非定常Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程出发，利用时间相关法，采用ＭａｃＣｏｒｍａｃｋ两步显格式，结合Ｂａｌｄｗｉｎ－Ｌｏｍａｘ代数湍流模型，数值模拟了高空台扩压器的内部流场，并计算了扩压器的性能。结果表明，采用求解Ｎ－Ｓ方程的方法计算高空台扩压器性能是一种有效的方法。
The viscous flowfields of diffuser in altitude test cell were simulated based on the Reynolds average unsteady Navier Stodes equations with time dependent method,MacCormack explicit scheme and Baldwin Lomax algebraical turbulent model.The diffuser performance was calculated.The results show that the method of soluting Navier Stokes equations is effective to predict the diffuser performance.
