Abstract

Visualizations of the leading edge cavity on a four-bladed inducer working with refrigerant 114 are presented. The evolution of the cavity length with the cavitation number is given for three different temperatures. These data are used to estimate the thermodynamic effect in R114. In addition, the onset of cavitation instabilities (alternate blade cavitation and rotating cavitation) are determined from the analysis of pressure fluctuations. The thermodynamic effect which affects the onset of instabilities is also estimated and compared to the one deduced from visualizations.
