Based on thermal analyses of growth and collapse of cavitation bubbles in liquids and considerations of heat conduction and thermal radiation effects, a new numerical method, Conduction-Radiation Method, for simulation cavitation bubbles was proposed. Combined with Runge-Kutta-Fehlberg Method and three methods (Isothermal Model, Adiabatic Model and Conduction-Radiation Method), Rayleigh-Plesset equation was solved. Comparisons of numerical simulations using the three methods were made. The result shows that the Conduction-Radiation Method has potential to simulate the cavitation bubble life cycles with satisfactory accuracy. The calculation results with Conduction-Radiation Method agree very well with the three groups of experimental results.
