Some Visual Observations of Cavitation in Rotating Machinery

Abstract

Visual studies of cavitation within a rotating blade row have contributed significantly toward an improved understanding of flow patterns and cavity formations. This report documents and discusses some of the forms of cavitation both steady and unsteady, that have been observed in several pump rotors operated in water at room temperatures. The behavior of these different forms of cavitation with varying operating conditions is noted, and a correlation is made between visual observations and measured performance.
