Effects of Flow and Non-Newtonian Fluids on Nonspherical Cavitation Bubbles,
Abstract
Flow cavitation is substantially altered, both at inception and during subsequent dynamics, by the addition of small amounts of water-soluble polymer. Theoretical and experimental single-bubble systems developed here trace the shape of a bubble as it is influenced by a volume change of the cavity, the rheology of the surrounding fluid, the presence of a solid wall, and/or an imposed external flow. The theoretical formulation pertains to a bubble in a fluid which is infinite in extent and contains no barriers or interfaces apart from the bubble surface. An external flow can be imposed, imparting a stress history. In addition, a spherical bubble profile, obtained from present experiments or theories, dictates a volume change and drives the non-sphericities. (Author)
