- Abstract:
- Calculation on cavitation bubble growth and collapse is key to study the cavitating water jet. Afterthe analysis of different numerical methods to Rayleigh-Plesset equation, a numerica! method with variable-steps is developed that can overcome the weak point of constant time step method to solve the Rayleigh-Plessetequation, And it also learned that a constant time step is not appropriate for solving the Rayleigh-Plesset equa-tion when dealing with large pressure variations or under the smaller pressure variation. The variable time stegmethod ean get a better result. What more, it is only after the variable time step method can be predictedwithout singularity, So the variable time step method is batter than the constant time step method in savingcomputational and keeping accuracy, This paper provides a new idea to solve Rayleigh-Plesset equation.
