摘要: Numerical simulations of bubble pulsations have been performed for a system two clouds in order to study the experimentally observed motion under an ultrasonic horn by high-speed video camera. The comparison between calculated results and experimental observation pulsation has indicated that is strongly influenced interaction with surrounding bubbles. expansion during rarefaction phase ultrasound reduced bubble-bubble interaction. Some bubbles move toward tip due secondary Bjerknes force acting from near tip. It also shown acoustic amplitude liquid cavitation decrease radiation resistance.
