Numerical Simulation On Collapse Of Void Bubble Filled With Vapor Content Using Particle Method
In present paper, the inertia controlled collapse of void bubble filled with vapor content has been simulated using Moving Particle Semi-implicit(MPS) method. The interfacial velocity, collapse time, bubble shape sequence, peak pressure and other key parameters were obtained and discussed profoundly. These thermal parameters show several cycles of oscillation with reduced amplitude during the whole collapse process. These behaviors are similar with cavitation bubble collapse. Comparison work was done based on experimental data by Board and Kimpton(1974). The comparison revealed that MPS method supplied with adiabatic compression assumption is applicable for the evaluation of collapse behaviors of low pressure steam bubble. The present work is helpful for further application of MPS method on bubble dynamics.
