Cavitation associated with rotating machinery remains a major research area within the general field of hydrodynamic cavitation and bubbly or liquid-gas two-phase flows. The large range of spatial and temporal scales and physical phenomena involved make cavitation an ongoing challenge for gaining insight or predictability via either experiment or computation. The fundamentally unsteady nature of cavitation involves phenomena ranging from nucleation and surface effects, mass transfer via gaseous diffusion and phase change to macroscopic flow physics involving turbulent flow interactions and two-phase compressible flow effects. Advances in experimental techniques are providing significant opportunities for gaining new insights and the high quality data sets required for computational validation and development. The objectives of this forum encompass recent advances in basic experimental research into unsteady cavitation phenomena as well as applied work on cavitation generally in rotating machinery. These include new insights into nucleation physics, the role of surface topography and chemistry, developed cavitation dynamics and mitigation strategies, the roles of freestream and wall-bounded turbulence and new experimental approaches and facilities.
