Аннотация

The effect of distributed tangential injection of heavy SF6 gas into the wall zone of a boundary layer on the supersonic flow stability and laminar-turbulent transition is experimentally and theoretically investigated at the freestream Mach number M = 2. For the first time it is experimentally shown that in the case of this injection laminar-turbulent transition is downstream displaced.
