SIMULATION OF A NONSTATIONARY FLOW IN A CHANNEL WITH A DISTRIBUTED BLOW FROM THE CHANNEL WALLS AND FORCED PRESSURE OSCILLATIONS

摘要

A nonstationary flow in a channel with a blow was simulated on the basis of the Reynolds-averaged Navier-Stokes equations and the two-parameter k-ε model of turbulence. The pressure near the left end of the channel changes by the harmonic law. It was established that the k-ε model of turbulence can be used for calculating the nonstationary flows formed in the indicated channel by a blow.
