Flow Visualization Around a Spark-induced Single Bubble by Flow Birefriingence Technique

Abstract

Until now the flow birefringence method has been used to observe the steady state flow. We applied this method to observe the flow around a Spark-induced bubble. When a cavitation bubble collapses near a solid wall, the bubble deforms from its spherical form and a microjet arises against the solid wall. We use the birefringence method to show the appearance of this microjet.
