On Modified Numerical Schemes in Vortex Element Method for 2D Flow Simulation Around Airfoils
Abstract:

The problem of incompressible steady flow simulation around an airfoil is discussed. For some simplest airfoils (circular, elliptical, Zhukovsky airfoils) the exact solution is known from complex analysis. It allows to compute the intensity of vortex layer which simulates the airfoil. Some modifications of the vortex element method are proposed and test computations are carried out. It-s shown that the these approaches are much more effective in comparison with the classical numerical scheme.

Keywords:
Vortex element method, vortex layer, integral equation, ill-conditioned matrix.
