Summary on Grant Application Form
More than 150 years after the first studies of liquids under tension (or 'negative pressure') scant knowledge exists concerning the cavitation properties of common engineering liquids, such as lubricants, coolants, or biomedical fluids. This lack of knowledge, which is a barrier to the improvement of flow devices and the development of new flow-based technologies, is mainly attributable to the difficulties associated with conducting rigorous experimental work in this area. The proposed work, which includes complementary theoretical, numerical and experimental studies, will address a longstanding paucity of reliable experimental techniques by exploiting and further improving our recent advances in the development of instruments for cavitation research, and will include long-overdue studies of engineering liquids under dynamic stressing at temperatures representative of their operating conditions (including the supercooled regime). Other significant issues to be addressed include (i) the possible exploitation of cavitation phenomena at liquid-liquid interfaces to control droplet production; (ii) a possible pressure-enhanced role of viscoelasticity in bubble dynamics and liquid jet development; and (iii) the first study of the dynamics and structure of cavitation damage by liquid jets at biomechanical structures including membranes composed of human epithelial cells.
