We propose the modified Rayleigh (MR) equation, which improves drawbacks of the former models. The agreement between calculated and measured bubble radii confirmed the validity of the RP equation. Numerical calculations are performed for various cases, such as a water injection at low injection pressure and a diesel fuel injection at high injection pressure. The proposed MR equation is confirmed to satisfy (i) low computational cost by using a large time step, (ii) avoiding a large numerical error using large time steps, and (iii) good estimations of the growth and collapse rates of cavitation bubbles under various pressure conditions.
