Abstract:

The composite velocity formulation for the Euler and Reduced Navier-Stokes system of equations has been investigated. For transonic steady flow over airfoils a combination of conservative and nonconservative flux directional systems of difference equations have been developed and applied to obtain full potential, Euler and Reduced Navier Stokes solutions. The Enquist Osher procedure for shock capturing has been adapted for these applications to obtain sharp shock waves for both potential and Euler equations. For two dimensional transient flows and for three dimensional global relaxation computations, the coupled strongly implicit matrix inversion algorithm has been reformulated in order to allow for time consistency and space marching efficieny, respectively. Keywords Composite velocity procedure Numerical methods Euler equations Navier Stokes equations Strongly implicit procedure.
