Solution to the Compressible Navier-Stokes Equations of Motion by Chebyshev Polynomials with Implicit Time Stepping

Abstract

Implicit time stepping has been incorporated into the author's pseudospectral compressible Navier-Stokes code. This report presents results for three classes of laminar flows. A normal shock wave laminar boundary layer interaction on a flat plate, an oblique shock wave laminar boundary layer interaction on a flat plate and the flow over a circular arc airfoil at two mach numbers. Keywords: Airfoils; Inviscid time dependent compressible flow; Euler equations of motion.
