    The Effect of Inlet Flow Pulsations on the Flow Structure behind a Backward-Facing Step.

  • Original language description

    The wall shear rate profiles were measured along the bottom and roof walls of rectangular channel with backward-facing step. The profiles were measured by two-strip electrodiffusion probes. It is possible to see the strong effect of the inlet flow pulsations on the flow structure. The influence of the inlet flow pulsation was studied for various frequence and amplitude for water when the Reynolds number was ranging from 100 to 1500 and expansion ratio of the channel was 2.

    Vliv pulzací nátoku na strukturu toku v kanále za náhlým rozšířením.

  • Czech description

    S využitím elektrodifuzní metody byly proměřovány gradienty rychlostí podél dolní a horní stěny pravoúhlého kanálu s negativním stupněm. Byl zjištěn značný vliv pulzací nátoku na strukturu proudění za náhlým rozšířením. Tento vliv byl zkoumán pro různé frekvence a amplitudy pulzací nátoku pro vodu ve velkém rozsahu Reynoldsova kritéria od 100 do 1500, kdy expanzní poměr kanálu byl 2.
