非定常Euler方程数值计算中高精度格式应用
High-accuracy numerical method applied to calculate unsteady Euler equations
摘要
Abstract
By applying 5-order accuracy WCNS ( Weighted Compact Nonlinear Schemes) to simulate forced-oscillation of NACA0012 aerofoil, Some techniques of high-accuracy method in unsteady simulation were studied, such as inner iteration capability, inner iteration parameters of " dual time stepping" method, and discretization accuracy of time derivatives of Euler equations. The results show that, these coefficients hare a remarkable effect on computation accuracy and CPU time when WCNS scheme is applied to unsteady flow simulation.关键词
