Integration of Euler equations for 2D motion of compressible medium flow

The Euler equations for 2D unsteady motion of compressible medium flow are under consideration. Two components of velocity vector, density and pressure supposed as the main unknowns. We propose the procedure of integration which based on introduction of new variables and general statements of theory of partial differential equations. As the result we obtain ratios for simple algebraic combinations of main unknowns which convenient for solution of fluid mechanics problems and for simulation of real fluid and gaseous flow.
