Hi !!!! I am interested in modelling ultrasonic cavitation using COMSOL. The main objective is to model the pressure distribution in a liquid metal due to ultrasonic vibration through a horm immersed in the liquid metal. The horn is vibrated at a specific frequency and dipped in the liquid. Ultrasonically induced cavitation consists of the formation of small cavities (bubbles) in the molten metal followed by their growth,pulsation, and collapse.I will add some nano particle inside the liquid metal while horn is vibrating. I want to model the horn (its geometry is known) which is vibrating in a known liquid at a given frequency and be able to estimate the pressures in the liquid metal (max, min, and collapse pressure). Moreover, I want to see the distribution of nanocomposite due to ultrasonic vibration.
Will somebody help me to model this ? Or point out some examples in this area.
