• K-1436 Non-axisymmetric motion of two laser-produced cavitation bubbles near a solid wall

抄録

The motion of two laser-produced cavitation bubbles near a solid boundary was studied experimentally using high-speed photography. Two bubbles were mainly generated side by side near a solid wall. Eventually they collapsed non-axisymmetrically due to the Bjerknes force resulting from the bubble-bubble interaction as well as the bubble-boundary interaction. The direction of the liquid jet formed inside a smaller bubble, θ_j was estimated to examine the effect of the bubble size ratio, ξ, resulting in a remarkable decrease in θ_j as decreasing ξ, especially in the region of ξ<0.6.
