Abstract: In physics, a “source” denotes the origin of matter or energy, while a “sink” refers to the terminal point of matter or
energy. By analogizing with the energy source problem in underground explosions, this study proposes an energy sink problem
for ideal fluid cavity annihilation. A detailed analysis is conducted on the energy balance and adjustment mechanisms in the
ideal fluid cavity annihilation problem, establishing the relationships among fluid pressure work, energy convergence,
transmission and transformation. A characteristic energy factor is introduced to describe the “centripetal convergence”
behavior of energy sinks. The characteristic energy factor for energy sinks incorporates the information on converged energy,
geometric dimensions of cavities and physical properties of fluids, effectively characterizing the “convergence” behavior of
energy sink problems and laying a theoretical foundation for the subsequent research on “energy sink” problems in solids. The
physical mechanisms and mathematical foundations of the characteristic energy factor are analyzed, and its characteristics and
advantages are expounded. Specifically, the introduction of the characteristic energy factor circumvents the need for complex
