Hydrodynamic Mechanisms Controlling Cavitation Erosion
Paper i proceeding, 2012

In this paper we consider development of cavitation erosion having its origin in sheet cavitation. The discussion includes generation of cloud cavitation from sheet cavitation and how a cloud collapse can be enhanced by energy cascading from the collapse of a glassy sheet cavity into the collapse of a cloud. A decomposition of the cavitation process into crucial parts results in formulation of a conceptual model for description and analysis of the generation of erosion by mixed glassy and cloud cavitation.
