      A method of numerical simulation of non-unidimensional non-stationary flows of incompressible non-viscous gas in the air-gas channel of power units based on implementation of direct replacement of local approximating functions into the integral form of the preservation equations for the element of the computational domain is described. The performance of the method is shown using the computational example of 2D non-stationary gas flow in axisymmetric ring channel of variable area.
