Liberation of Free Gas from a Liquid

Part of the Ultrasonic Technology book series (ULTE, volume 1)


The acceleration of the liberation of free gas present in a liquid in bubble form in a sound field is attributable to a number of factors. The occlusion of the bubbles to the surface is clearly accelerated by their coalescence under the action of the Bjerknes force, owing to the entrainment of bubbles by acoustic streaming, and under the influence of the acoustic radiation pressure. Due to the complexity of the degassing process as a whole, we shall proceed as before and analyze its individual stages, assessing the influence of the various factors in the example of a single gas bubble or pair of bubbles.
