基于五阶空间离散精度的WCNS格式,开展了CRM翼/身/平尾组合体模型的高阶精度数值模拟,以评估WCNS格式对复杂外形的模拟能力以及典型运输机巡航构型阻力预测方面的精度。首先依照DPW组委会提出的网格生成指导原则,利用ICEM软件生成了粗、中、细3套网格,对应的y+分别为1、2/3和4/9。通过对CRM模型的计算和分析,研究了网格规模对气动特性、压力分布和翼根后缘局部分离区的影响。通过与DPW4统计结果和部分实验结果的对比,高阶精度数值模拟结果表明,本文的气动特性计算结果与统计平均结果吻合较好;网格密度对机翼内侧的展向站位压力分布影响较小,对机翼外侧展向压力分布影响较大;网格密度对翼根后缘局部分离区略有影响。

CRM(Common Research Model)是第四届~第六届AIAA阻力预测研讨会(DPW)选择的参考外形。第四届和第五届DPW会议气动特性数值模拟结果的统计分析表明试验与计算之间存在明显差异。采用CFD方法和流固耦合(FSC)方法数值模拟了带支撑装置的CRM翼身组合体(CRM-WBS)构型的气动特性,以评估模型支撑装置和静气动弹性变形对CRM翼身组合体(CRM-WB)构型气动特性数值模拟结果的影响。通过与不包含支撑装置的CRM-WB构型的数值模拟结果和NASA Langley NTF风洞试验结果的对比分析,CRM-WBS构型的CFD计算结果表明,支撑装置导致机翼上翼面激波位置前移,升力系数、阻力系数、低头力矩系数下降。CRM-WBS构型的流固耦合计算结果表明,静气动弹性变形主要影响机翼上表面激波位置并显著降低外侧机翼激波位置前的负压值,进一步导致升力系数、阻力系数、低头力矩系数下降。包含支撑装置和静气动弹性变形的CRM-WB构型气动特性数值模拟结果更加接近试验结果。
