本文采用适用于EARSM模型的第二代URANS数值模拟技术，研究了展弦比为5：1：1的跨音速空腔流动。一个非结构化网格由六面体细胞被用来执行这些计算。本文的第一部分报告了最近对代码的改进。M219腔上获得的结果，然后提出，包括预测的平均流量和音调模式。研究还简要地考察了时间步长对流动特征预测的影响。
A transonic cavity flow with a 5:1:1 aspect ratio is studied in the present work using a 2ndgeneration URANS modeling technique adapted to an EARSM model. An unstructured mesh made from hexahedral cells is used to perform these computations. The first part of the paper reports on recent improvement brought to the code. Results obtained on the M219 cavity are then presented and include the prediction of the mean flow and the tonal modes. The study also briefly looked at the influence of the time-step on the the prediction of the flow features.
