摘要

Specifically, the JWL EOS was introduced as a suitable equation of state. By assuming the basic hypothesis of instantaneous detonation of explosives and the formation of initial shock waves at the interface between the explosive and the liquid, a high-pressure bubble consistent with the JWL EOS was constructed, and the initial conditions for bubble calculation were established. Building upon this, the dynamics calculation method for underwater explosion bubbles based on the JWL EOS was developed using the second-order accurate bubble motion equation, coupled with the commercial mathematical software MATLAB. By comparing the simulation results with the previous experimental data, a comprehensive analysis was conducted. The research findings demonstrated that the introduction of the JWL EOS, which is consistent with the properties of detonation products, is reasonable and feasible. The developed calculation method achieves a close correlation with the detonation and properties of explosive products, demonstrating satisfactory computational accuracy and practical utility.
