Abstract

The process of growth and collapse of spark-generated cavitation bubbles in clear water and sediment-laden water flow were photoed by high-speed framing photomacrography. Some important phenomena of cavitation were recorded. The paper describes optic multiplying system, high-intensity flash lamps, some analog experimental apparatus, synchronizing and automatic control technique used for high-speed framing photomacrography. Several theoretical analysis and calculation dealing with effect of viscosity, quantity of sediment inclusion in water flow and nearby boundary face on growth and collapse of bubbles as well as formation process of microjet were made in this paper. All the results provide experiment and theoretical foundation for further investigation of mechnism of cavitation.
