N2 - In this paper, an unified high-order algorithm for all speeds is developed. The preconditioning matrix of Weiss and Smith combined with a 5th-order WENO scheme for inviscid flux and a fully conservative 4th order central differencing for viscous terms are employed. The unfactored implicit Gauss-Seidel relaxation scheme is used for time marching. The numerical simulation of a natural convective cavity flow, subsonic flow, transonic and supersonic flows show that the high order preconditioning method is efficient, robust, and accurate for both low speed incompressible flows and high speed compressible flows.
