本文发展了一种适用于跨音速叶栅非定常流场数值模拟的隐式迎风格式。二维的，雷诺平均的Navier-Stokes方程离散在空间中使用一个细胞中心的有限体积配方和时间使用欧拉隐式方法。无粘通量的计算采用基于TVD格式的高精度迎风格式，并采用Roe近似Riemann解，粘性通量的计算采用中心差分法
An implicit upwind scheme has been developed for Navier-Stokes simulations of unsteady flows in transonic cascades. The two-dimensional, Reynolds-averaged Navier-Stokes equations are discretized in space using a cell-centered finite volume formulation and in time using the Euler implicit method. The inviscid fluxes are evaluated using a highly accurate upwind scheme based on a TVD formulation with the Roe's approximate Riemann solver, and the viscous fluxes are determined in a central differencing manner
