Description
  • V práci jsou studovány dynamické aspekty odtržení mezní vrstvy na válci při řízení pomocí syntetizovaného paprsku. Pro měření je použita metoda TR-PIV. Pro analýzu korelací v časové a prostorové oblasti je potom použita metoda BOD. (cs)
  • Dynamical aspects of the boundary layer separation on a circular cylinder in cross-flow are studied experimentally. Two cases are compared, the base case and the case with excitation using a synthetic jet actuator. The TR-PIV technique was used to catch both space and time velocity field correlations. Instantaneous velocity fields and skin friction distributions are evaluated. For dynamical structures study, the BOD method was applied based on energetic principle. Dynamical modes connected with vortex shedding process, dynamical excitation by synthetic jet and transition to turbulence are identified.
