A two-bubble model with radiate (alpha bubble)-receive (beta 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 psi on the energy transfer rate is investigated via numerical simulation. The relative received energy epsilon, relative jet energy J, and energy transfer rates eta are defined to quantify energy transfer. Results show that the energy transfer rate decreases with the increase of d and psi 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 epsilon proportional to 1/d(2). With the increase of psi, the maximum inner pressure of the beta bubble increase first and then decreases, while the jet energy of bubble beta changes with the law of J proportional to psi. It is found that the energy storage capacity increases with the bubble radius by simulating different bubble radius ratios.
