Abstract:
The new approximations of Navier–Stokes equations for incompressible fluid on triangular and tetrahedral grids are proposed using predictor-corrector method. An estimations of unconditional stability of constructed schemes were fulfilled. The numerical solution of 2-D problem of flow field in a cavity with a mobile top cover was done (performed). The comparison with the other results was carried out. The questions of monotonisity of grid equations are discussed.
