Cavitation Research Laboratory

Cavitation research at the AMC, University of Tasmania, involves classical work such as cavitation about marine propulsors and control surfaces but also more novel problems. Typical of these includes mechanisms for air entrainment about ship hulls, the effects of propellers and control surfaces in mixing and bubble breakup and subsequent dispersion and dissipation of bubbles in the ship wake. Other relevant problems in hydrodynamics include the effects of bubble populations present in the ocean that provide seeding for cavitation inception and hence control its dynamic behaviour. Dissolved (incondensable) gases, invariably present in practical liquid volumes, may also play a role in cavitation behaviour via diffusion across the liquid-vapour interface. Finally, turbulence and surface tension also play an important role in cavitation physics.

To study such problems new laboratory facilities have been developed funded by national competitive grant schemes and the Defense Science and Technology Organisation. These include a variable pressure water tunnel with the capability for control of free (as bubbles) and dissolved gas content and a pressurisable chamber for the study of small-scale bubble and related phenomena
