Rectified mass diffusion of gas bubbles in liquids under acoustic …

WebbWhen a liquid is spared with an inert gas in a two-phase flow, rectified diffusion is desired to increase the mass transfer and removal rate of dissolved gasses. Applying rectified diffusion can be difficult because entrapped and dissolved gas bubbles tend to avoid entering the ultrasonic cavitation field at lower intensities.
