The NACA 0012 airfoil is widely used. The simple geometry and the large amount of wind tunnel data provide an excellent 2D validation case. For this case I use the Spalart-Allmaras turbulence model. Mesh The mesh is a 30,000 cell structured C-grid. The chord length is 1 m. The width ...
1)高速光滑NACA0012翼型计算验证 为了验证高速条件下湍流模型选取的正确性,选取NACA0012翼型在亚音速和超音速阶段马赫数为0.5~0.8和1.3-1.5的条件下进行了计算研究,获得了翼型表面压力系数曲线,并将计算结果与Ren Xudong[Ren X, Zhao Z, Gao C, et al. Investigation of NACA 0012 Airfoil Periodic Flows in a T...

1.In this paper, we introduce the PIV experimental results on the wake flow structure of a NACA0012 airfoil mounted above water surface.实验分别测量了翼型与自由表面不同间距的多种工况下,零攻角NACA0012翼型尾流速度场随时间的演化过程,并将同一间隙条件下连续采集的瞬态速度场结果进行时均统计分析,获得了...
3、efined-Functions-Complied 此时打开了 Complied UDFs的窗口,Add在选择UDF的对话框中找到NACA0012D文件夹中 的 airfoil.c文件,选中,ok;此时返回到Complied UDFs的窗口点击Build , FLUENT开始 进行编译, 可以在FLUENT窗口看到编译的一些过程提示;等编译完成,点击Load;就将已经编译好的UDF力口载到FLUENT中了。4) ...
I am new to COMSOL and I thought I would start with a relatively simple model: a NACA 0012 airfoil at 0 angle of attack. The domain is small and the mesh resolution is relatively coarse to get faster solutions. (Once it works I will try a larger domain and finer mesh) ...
