摘      要：Liquid surfaces can be depressed by applying acoustic radiation force. The balancebetween the acoustic radiation force, surface tension force, and buoyantforce sustainsthe stable dimple depression. Beyond a certain threshold, higher acoustic radiationforce leads to instability and bubble formation. The bubble size is determined by theacoustic radiation force and the liquid surface tension. Effective management of bubble generation can be achieved by controlling acoustic radiation *** methodfor creating depression on liquid surfaces and generating bubbles is described, whichrequires neither gas supply nor direct contact with equipment.
