摘要
基于CAE-DNW correlation workshop提供的两个数模构型——标准构型CAE-AVM Base与CAE-AVM DZ构型进行研究。CAE-AVM DZ构型是CAE-AVM Base构型在风洞试验时产生静气弹形变后的真实构型。采用SST湍流模型,预测CAE-AVM Base构型与构型CAE-AVM DZ的流动状态,分析流动现象,并研究风洞实验中气弹变形干扰下气动数据修正方法。与试验数据对比,验证计算状态,并对气弹数据修正进行进一步的改进,得到一套适用于关联CFD结果和风洞试验结果的数据修正方法,即在同升力系数下进行数据的关联修正。
This paper shows a study on two configuration provided by CAE- DNW correlation workshop, one is abase configuration CAE- AVM Base and the other is CAE- AVM DZ which is the real configuration in the wind tunnel test. The study takes SST model and predicts flow field, analyze the flow phenomenon and look up the method to correct the data interfered by aeroelasticity. Then the method can be improved with being compared with experiment data, and we can obtain the correlation method between the CFD result and Wing Tunnel result, which is a correlation method comparing CFD and wind tunnel result in the same lift coefficient.
