Abstract

The suction performance of turbopumps in cryogenic fluids is basically much better than that in cold water because of thermodynamic effect of cavitation. However, it is not still clear how the thermodynamic effect works on cavitation instabilities such as rotating cavitation and cavitation surge. In the present study, the unsteady heat exchange between cavity and surrounding liquid is taken into account in a stability analysis using a singularity method. The results are qualitatively compared with existing experiments to clarify the research needs for deeper understanding.
