The purpose of this investigation is to establish direct numerical simulation (DNS) using high-order finite difference method. The unsteady flow in turbulent channel is solved numerically at Reynolds number of 150, based on the wall friction velocity and channel half-width. In this paper DNS based on fifth order upwind difference scheme for convective term of the Navier-Stokes equation is presented. The method used in this investigation employ third-order Adams-Bashforth method for convective term and Crank-Nicolson method for viscous term. The part of Crank-Nicolson scheme in the discrete Navier-Stokes equations and Poisson equation for the pressure are solved by the plane Gauss-Seidel method. The computations were carried out on the NEC SX-4 computer with about 300,000 grid points. The computed results are good agreement with those of spectral simulations by Kuroda et al.
