摘要
基于有限元的ANSYS软件,可以分析二维翼型流场,解决作用于气动翼(叶)型上的升力和阻力,并可以得到流场中翼型表面的压力与速度分布。与此同时,通过对ANSYS的二次开发,编制相关的三分力系数求解模块,得到各系数曲线。现以标模翼型为例,利用此模块得到的三分力系数与NF—3风洞试验值作对比,验证了用ANSYS实现二维翼型风洞数值模拟的可行性。
The ANSYS software is based on the finite element method, it can analyze the two-dimensional foil flow fields and solve the problem about the lift and drag on the foil or blade, the pressure and velocity distribution on the foil surface in flow fields. The model of solving the three force coefficients and the coefficient curve are made by the secondary development of the function of ANSYS. Now, as the example of the standard foil, the method of realizing numerical simulation about the two-dimensional foil wind tunnel experiment is feasible, by comparing the three force coefficients obtained by the solving model with the data obtained by NF-3 wind tunnel experiment
