摘要
本文详细介绍了针对第三届AIAA阻力预测会议公布的标准DPW-W2模型的N-S黏性流计算考题,考察了两种不同数目的结构化网格和两种不同的湍流模型。结果确认400万数目的网格可以准确地预测模型的阻力数值。
This article introduced the standard DPW-W2 model and its N-S equations numerical validation announced by the 3^rd AIAA Drag Forecast Conference. We computed two kinds of different structured grids and two kinds of turbulence models. The computational results confirm that the grid with 4000000 cells can accurately forecast the air drag.
