内容記述 | The present paper describes a calculation method for predicting the aerodynamic performance of single airfoils in the transonic flows of high Reynolds numbers. For the inviscid part of the method, a transonic full potential equation represented on an algebraically generated C-topology coordinate system is solved by a fully conservative AF2 iteration scheme. A finite difference method (PC-CN Scheme) is used for the boundary layer and wake solutions. In the viscous method, an algebraic turbulence model for the asymmetric near wake is also developed. The model used to achieve viscous-inviscid coupling is the equivalent source model. The wake thickness and curvature are taken into account. The calculations for turbulent wake flows indicated good agreement with the experimental data, and show that the velocity profiles across the wake and minimum velocities can be computed satisfactorily with the present method. Comparisons of the predictions with high Reynolds number wind tunnel experiments show good agreement for pressure distributions, lift and drag. | |||||
