Abstract: Authors investigated an axisymmetric jet of air issuing from a 40 mm dia. nozzle using 3D particle image velocimetry system. The jet was excited by a rotating acousticpressure field in the nozzle exit plane to ensure generation of two helical instability modes chasing one another and mutually interacting. The excitation signal was also used for ensuring PIV data acquisition at a precise phase position
Keywords: PIV - particle image velocimetry; turbulence; zatopený proud
