块结构的MUSCL算法求解三维进气道流场

本文将ＭＵＳＣＬ格式扩展为三维算法，并用于湍流流场的数值模拟。通过求解超声双斜楔压缩面流动，得到了含有激波、嵌入激波、剪切流和湍流边界层等流动特征的复杂流动结构，数值解与实验数据吻合得很好。文中将此算法与块结构网格技术相结合，使之能求解具有三维复杂几何形状的流场。并应用该算法模拟了Ｆ－１６战斗机进气道在５种典型飞行状态下的三维湍流流场，计算结果清楚地揭示了这些情况下的三维流动现象，得出了进气道的性

The Numerical Simulation of 3-D Flows of a Inlet Using a Multi-Block MUSCL Algorithm

An improved MUSCL scheme was extended to the calculation of three dimensional flow in this paper. A supersonic flow in the corner of the intersecting wedges, which has shocks, shear flows, turbulent boundary layer and combination of them, was simulated by this algorithm. Results identified the dependability and accuracy of this method. Several cases of the internal and external 3D turbulent flows of F 16 Fighter inlet were calculated. The details of these flows were described clearly and the performance of the inlet was obtained by numerical simulation. Comparison of the computational and the experimental results shows that the method can predict the complex turbulent flow satisfactorily.
