摘要：
New approximations of Navier-Stokes equations for an incompressible fluid on triangular and tetrahedral grids are proposed using a predictor-corrector method. Estimates of the unconditional stability of constructed schemes and numerical Solutions of a two-dimensional problem of fluid flow in a cavity with a moving upper lid are presented. A comparison with results of other authors is given. The problems of monotonicity of grid equations are discussed.
