摘要: 采用"亚跨超CFD软件平台"(TRIP2.0)数值模拟DLR-F6翼身组合体构型,采用的多块对接网格、测压和测力的试验结果均来自美国AIAA阻力计算小组,对比计算结果采用CFL3D的结果.详细研究网格密度、湍流模型对DLR-F6翼身组合体构型的总体气动特性和压力分布的影响,计算结果与相应的试验结果较一致.采用SST两方程模型得到网格收敛结果;不同的湍流模型对压差阻力影响较小,对摩擦阻力影响较大;不同的网格密度和湍流模型对压力分布影响较小.

Abstract: Navier-Stokes calculation on multi-block is performed to calculate drag of the DLR-F6 wing-body configuration with CFD software TRIP2.0.Structured grids(1-to-1) and test results used are from Drag prediction workshop Ⅱ (DPWⅡ). Referenced numerical results are obtained with CFL3D. Effects of mesh density and turbulent models on aerodynamic characteristics and pressure distribution are carefully studied. Results are verified by experimental data and CFL3D results. Grid refinement leads to convergent results in SST turbulent models. It is demonstrated that turbulent models have little influence on pressure drag, but obvious influence on friction drag. The turbulent model and grid density have little influence on pressure distribution.

Key words: TRIP2.O, DLR-F6, drag prediction workshop Ⅱ, drag, turbulent models
