ANALYSIS OF PRESSURE PULSATIONS OF CAVITATING FLOW IN CONVERGING-DIVERGING NOZZLE

Original language description

Cavitating flow in converging-diverging nozzle (axisymmetric Venturi tube) is investigated. Characterization of the cavitating flow was done with high speed camera and the basic flow patterns were determined: incipient cavitation, partial cavitation, fully developed cavitation and supercavitation. Pressure transducers of tenzometric and piezoelectric types were used to determine amplitude-frequency characteristics of the pressure pulsations in particular regimes. Results were correlated with spectral properties obtained from high-speed camera video sequences and image processing analysis. Finally, attempt of unsteady cavitating flow CFD simulation is presented.
