Simulations of radial motion of 5 micron air bubble in water with O₂ bubble and N₂ bubble. 𝑓=20 kHz; 𝑃_A=150 kPa; and 𝑃_𝑜=100 kPa. Time history of (a) radius of the bubble; (b) temperature inside the bubble; (c) water vapor evaporation in the bubble; (d) pressure inside the bubble; (e) microturbulence generated by the bubble; and (f) acoustic waves emitted by the bubble.
