摘要
本文用保角变换法求解不可压、二元剖面势流问题,在求变换函数的过程中作了近似的变换处理,其方法的主要特点是获得了对任意翼型表面的速度和压力分布的近似解析表达式。为了区别其它有关计算方法,特将此方法取名为“R”近似计算方法。文中利用所推导的V、P的解析近似表达式,对任意对称翼型“薄翼”剖面翼型和任意非对称翼型作了计算,并与传统近似解和试验结果作了比较,从而证明本文所提出的“R”方法与试验结果能够很好地符合。
This paper deals with the conformal transformation method used in solving problems of incompressible and two-dimensional flow in infinite field. It also shows an approximate treatment in the course of finding the tranformative function. The main feature of this method is that it has obtained an approximate analytical expression for the velocity and pressure distribution on an arbitrary aerofoil surface. This method is named "R" Method in order to distinguish it from others. Using the approximate analytical expression of V.P. derived above, we have carried out some calculations about the arbitrary symmetrical thin aerofoil and arbitrary non-symmetrical aerofoil. This approach is also compared with the traditional approximate solution and the experimental results. It is thus proved that "R" method can be consistent with the experimental results satisfactorily.
