采用自研的非结构网格解算器UNSMB进行了AIAA第三届阻力会议提供的DLR-F6翼身组合体的阻力计算验证。重点分析了模型的网格收敛特性、升阻力曲线以及压力分布等,并把计算结果与阻力预测会议上各个软件的计算结果以及试验数据进行比较,在此基础上分析计算结果。分析结果显示,非结构混合网格解算器的计算结果与各个软件的计算结果以及风洞试验数据吻合度较好,一定程度上验证与确认了解算器的阻力预测精度。
The resistance calculation of the DLR-F6 wing-body assembly provided by the AIAA Third Resistance Conference was conducted using the self-developed unstructured grid solver UNSMB. Focusing on the model of the grid convergence characteristics, ascending resistance curve and pressure distribution, and the calculation of the results of the resistance prediction meeting of the software and the results of the test data were compared on the basis of analysis of the calculation results. The analysis results show that the unstructured hybrid grid solver results are in good agreement with the calculated results of various softwares and the wind tunnel test data. To some extent, the prediction accuracy of the solver is verified and verified.
