摘要
针对Joukowsky翼型复杂的型线特点,推导微分法生成其绕流流场计算网格的公式,并采用FORTRAN语言编写计算机程序.结果表明:所生成的计算网格不但具有贴体的特征,同时还具有其环形网格线由里及表渐疏布局的特点,而这一特点正是符合黏性流体绕流流场的计算要求;另外,微分法所生成的网格系的辐射状和环形网格线之间以及辐射状网格线与翼型型线之间的正交性较好,有利于进一步提高数值计算精度.
Based on the complex shape-lines of the Joukowsky＇s airfoil,the coil-flow flow fields were got by using differential method and computer programs were written in the FORTRAN language.The results showed that the computational mesh not only had a body-fitted feature,but also had a layout feature that was from the inside to outside.And the feature was in conformity with the requirements of the calculation of viscous fluid in the coil-flow flow field;Lastly,the mesh generated by differentiation method had a better orthogonally between the radial and the coil lines,as well as between the radial and the airfoil lines;this mesh is better for the accuracy of numerical calculation.
