Abstract

This thesis treats the problem of incompressible two-dimensional steady flow past airfoils or airfoil combinations at large angles of attack. A panel method was developed to compute the inviscid flow over two cylinders, airfoil-flap combinations and airfoils in ground effect. In addition, Cebeci's viscous/inviscid interaction method was applied to several airfoils and compared with available experimental data. The agreement is generally quite encouraging.
