The original numerical algorithm for integration in internal regions of Navier-Stokes equations stated in natural variables is presented. Discretization is carried on the unseparated grids. Two stages are derived at construction of numerical solution and the marched scheme for calculations is realized at one of them. Algorithm allows to optimize the iterative process at the expense of idea realization of simultaneous finding of pressure gradient and velocity field. Procedure has advantage according to highspeed in comparison with the known SIMPLE algorithm. Calculations of laminar and turbulent flows in channels are given.
