- Abstract
A two-bubble model with radiate (α bubble)-receive (β bubble) structure is constructed to study the energy transfer from one bubble to another. The influence of the non-dimensional distance d and the initial energy ratio ψ on the energy transfer rate is investigated via numerical simulation. The relative received energy ε, relative jet energy J, and energy transfer rates η are defined to quantify energy transfer. Results show that the energy transfer rate decreases with the increase of d and ψ when the two bubbles’ initial radius is identical. With the increase of d, the interactions between two bubbles are weakened, and the relative received energy satisfies the law of ε ∝ 1/d2. With the increase of ψ, the maximum inner pressure of the β bubble increase first and then decreases, while the jet energy of bubble β changes with the law of J ∝ ψ. It is found that the energy storage capacity increases with the bubble radius by simulating different bubble radius ratios.
