Abstract : The thin layer Navier Strokes/Euler code has been modified to implement the method of viscous effect and truncation error. These effects can be injected into the solution of the Euler equations on a grid which is normally to course to account for the viscous effects in the boundary layer. Additionally, studies have been conducted to refine transonic flow computations. By a study of the possible local, near sonic solutions in the hodograph plane, singular solutions have been found which may bridge the gap between smooth shock free flow and the flow with embedded shocks. Keywords: Transonic flow; Computational aerodynamics; Viscous inviscid interactions.
