Solution of time-dependant problems of gas and fluid mechanics on unstructured grids

The finite volume method for discretisation of time-dependant Navier–Stokes equations on unstructured grids is developed, and its outlooks for improvememnts are discussed. The features of discretisation of inviscid and viscous fluxes and time derivatives are considered. The possibilities of the approach developed are shown on the solution of some problems connected with the simulation of time-dependant flows in the gas turbines engines.
