CFD Validation for a High-lift Model

针对高升力标模NASA Trapwing全展襟翼构型展开确认计算研究。采用N-S方法,预测高升力模型的流动状态,分析高升力的流动现象及机理,评估自主研发的WiseManPlus软件及WoF90软件预测高升力流动的能力。通过对网格生成、计算策略及数据分析等各个环节进行分析,制定出一套适用于高升力模型工程应用的CFD计算方法,得到与实验值吻合较好的计算结果。结果表明,目前所采用的结构网格求解器WiseManPlus软件及混合网格求解器WoF90软件计算精度相当,适用于模拟高升力流动。

In this paper, CFD validation for a high- lift standard span configuration is investigated. Capabilities of two in- house model named NASA Trapwing with full- CFD solvers, WiseManPlus and WoFg0, are assessed for predicting flows around high lift device by using N- S methods to forecast given flow con- ditions and analyze coherent flow physics. After an detailed study for all process including mesh genera- tion, computational strategy and data processing, a method suitable for high lift configuration calculation in engineering is proposed, and results with good agreement with experiment are obtained. The results show that the solver WiseManPlus for the structured grid and the solver WoF90 for unstructured grid, used here have similar accuracy, and both are suitable for simulation of hizh lift flow.
