Abstract

The transient behavior of cavitation phenomenon in textured thrust bearings with oil lubricant was experimentally investigated. During experiments, the cavitation phenomenon in different surface textures was observed directly with a high-speed camera. It is shown that cavitation shape and area change according to texture patterns. The bubbles within cavitation zones increase with running time in the beginning and gradually reach a steady state, meaning that a transient period is needed to achieve equilibrium. In addition, the bubble composition was analyzed under the temperature of 35 °C and pressure of 30 kPa. The results show that oil vaporization plays a minor role in the formation of bubbles.
