Euler equations of generalized Riemann variable are derived from unsteady primitive variable Euler equations and solved by using two - a point-two-step upwind finite difference method.
Under the framework of finite volume method, the Riemann approximate solver is applied to obtain the numerical solution of the equation.

The hyperbolic equations were formulated by artificial compressibility method with the convective terms discreted using a third-order upwind scheme based on Roe's approximate Riemann solver.
