Development of Attached Cavitation at Very Low Reynolds Numbers from Partial to Super-Cavitation [PDF]
The present study focuses on the inception, the growth, and the potential unsteady dynamics of attached vapor cavities into laminar separation bubbles. A viscous silicon oil has been used in a Venturi geometry to explore the flow for Reynolds numbers ranging from Re=800 to Re=2000.
