  1. The fourth - order explicit upwind - biased compact difference schemes are used in the spatial discretization of the nonlinear convection terms. these difference schemes can be used in all computational region including the boundary neighborhood, and can overcome the difficulty not adapting simultaneously in the boundary neighborhood for general three - dimensional fourth - order central difference schemes, and improve computational stability a nd resolution. the compact difference equations with high accuracy and resolution for solving the incompressible n - s equations and perturbation equations are composed of these compact difference schemes, and provides an effective numerical method for the investigations of the turbulent spots and coherent structures

    文中發展了四階時間用於navier - stokes方程及其擾動方程的時間離散;對裂得出的關于壓力的poisson方程和關于速度的helmholtz方程,建立三維耦合四階致迎風差格式;這些格式適用於包括近邊界點在內的計算區域,克服了三維各自用四階中心差格式離散不適用於邊界域的困難,並提高了穩定性和解度,用這些格式別組成了數值求解navier - stokes方程及其擾動方程的高精度、高解度的致差方程組,為湍斑及湍流相干結構的研究提供了有效的數值方
