Summary

The present paper is devoted to the numerical study of separated flows near the bodies and in a wake behind them in the approximation of complete and simplified Navier-Stokes equations of a compressible heat-conducting gas. In the first section there is studied the influence of a nolder on the flow in a near wake. The stationary solution of the problem was found within the framework of complete equations by the splitting up method m terms of the physical processes and spatial directions [1]. In the second section there are studied three-dimensional separated flows near an isolated body on the basis of stationary parabolized Navier-Stokes equations by the method of global iterations. The modifications of the splitting up method are employed for its implimentation.
