Efficient modelling of aerodynamic flows in the boundary layer for high performance computing

Abstract

A unique technique to couple boundary-layer solutions with an inviscid solver is introduced. The boundary-layer solution is obtained using the two-integral method to solve displacement thickness with Newton’s method, at a fraction of the cost of a full viscous solution. The boundary-layer solution is coupled to an existing inviscid solver. Coupling occurs by moving the wall to a streamline at the computed boundary layer thickness and treating it as a slip boundary, then solving the flow again and iterating. The proposed method obtained good results when compared to analytical solutions for flat and inclined plates presented in this paper.
