Convergence acceleration for solution of unsteady incompressible fluid dynamics problems

Various convergence acceleration approaches for solution of unsteady incompressible fluid dynamics problems which use the method proposed in [1] are considered. The method is based on artificial compressibility, finite volume and approximate factorization methods. Comparison of these approaches for a problem of the numerical simulation of flows in a real hydraulic turbine is presented
