Hydrodynamics, acoustics and scaling of traveling bubble cavitation [PDF]

open access: yes, 1994
Recent observations of the geometries of growing and collapsing bubbles over axisymmetric headforms have revealed the complexity of the "microfluidmechanics" associated with these flows (Hamilton et al., 1982, Briancon Marjollet and Franc, 1990, Ceccio ...

Cavitation induced starvation for piston-ring/liner tribological conjunction [PDF]

open access: yes, 2011
The study investigates the mechanism of ring-liner lubrication in the vicinity of the top and bottom dead centres of an internal combustion engine. Predicting lubricant transient behaviour is critical when the inlet reversal leads to thin films and ...
