Paper Abstract

The main objective of this programme is to carry out a scale model study on the behaviour of a cavitation bubble during its collapse phase as effected by various types of surfaces. The cavitation test rig consists of a decompressed chamber which utilizes a spark discharge technique to generate a vapour cavity in water. The technique involves local heating and vaporization of the liquid through application of a thermal impulse. The evolution of the bubble is recorded by an NAC E-1O high speed cine-camera. The images captured by the cine-photography are later digitized for computer analysis. Results show that the characteristics of the surface influence the dynamics of the nearby cavitation bubble. The measured time interval for the bubble to collapse indicates that the pulsation pressure generated by a cavitation bubble near a compliant surface will be less than that near a rigid surface.
