Numerical solution of 3D Navier-Stokes equations on staggered grids

One algorithm to solve the 3D mixed boundary value problem for the Navier-Stokes system of equations is presented in this paper. The 3D mixed finite volume exponential type approximations on staggered grids are used. To solve the resulting system, an algorithm based on a three-level iterative method is proposed. Results of some numerical experiments demonstrating a numerical convergence are given.
