Abstract : A Reduced Navier Stokes (RNS) system is more computationally efficient than full Navier Stokes solvers and more accurate and less cumbersome than matched viscous and inviscid methods has been shown to apply to a significant class of aerodynamic problems. The RNS system is a composite of the full Euler and boundary layer equations and is discritized to optimize the numerical representation of viscous and inviscid regions, respectively.
