Single cavitation bubble interaction close to hydrophobic surface
Original language description
The cavitation bubble has a great potential to be used for local surface hardening. Highly controlled and geometrically placed defined bubbles can easily machine the area of interest modifying the surface of material. However, the effect of pointed pressure hit can be sometimes undesirable. Usage of hydrophobic cover could shield and spread the force in certain part of working. The aim of this project was to design a setup of Laser Induced Breakup and study the effect of cavitation bubble on hydrophobic surface. The main interest was focused on the air film behavior that is created on the surface in interaction with liquids. Here we used 532nm Nd:YAG pulse laser for the cavitation bubble generation. The process and the impact of cavitation bubble was visualized using high speed shadowgraphy. We also measured the air film thickness using microPIV technique and study its behavior under increasing liquid flow impact.
