PHASE-SYNCRONISED INVESTIGATIONS OF TRIGGERED VORTICES IN IMPINGING JETS

Original language description

Impinging jets can transfer the highest achievable thermal flux into (or out from) solid bodies. The transport is significantly influenced by complex and so far not fully understood vortical structures that develop due to hydrodynamic instability. This contribution describes experiments with visualisation of impinging air jets in which periodic formation of vortices was triggered by azimuthal travelling waves generated in nozzle exit - and was phase-synchronised with the camera. Visualisation was by laser light scattered from water mist particles added to the supplied air. The instability structures were identified in the images by using their coherence.
