CAVITATION RESEARCH AT THE GARFIELD THOMAS WATER TUNNEL

Current research at the Garfield Thomas Water Tunnel of the Applied Research Laboratory, The Pennsylvania State University is in the areas of hub vortex cavitation, the effects of polymer additives, roughness effects and thermodynamic effects. Primary emphasis in this paper will be on the first two areas for the flow regime of limited cavitation. The effects of Reynolds number and vortex breakdown on hub vortex cavitation are presented. Experimental results for the effects of polymer additives on shear flow and on flows about axisymmetric bodies are discussed. A brief description of research on roughness and thermodynamic effects completes the paper. (Author)
