Polymer effects on microjet impact and cavitation erosion

Abstract

THERE is a growing interest in using high molecular weight polymers as additives in various fluid-engineering systems. These activities are mainly stimulated by the anomalous drag reducing characteristics some high polymers exhibit in turbulent flows1. Early experiments also showed that polymeric additives suppress flow-generated cavitations2,3. An interesting question may therefore be raised as to the effects of high molecular weight polymers on cavitation erosion. We report here attempts made to examine such effects on static vibration-generated cavitation and flow cavitation.
