Numerical Analysis on Collapse of Cavitation Bubble in a Water Jet Flow
摘要
Abstract
Calculation on cavitation bubble growth and collapse is key to study the cavitating water jet. After the analysis of different numerical methods to Rayleigh-Plesset equation, a numerical method with variable-steps is developed that can overcome the weak point of constant time step method to solve the Rayleigh-Plesset equation. And it also learned that a constant time step is not appropriate for solving the Rayleigh-Plesset equation when dealing with large pressure variations or under the smaller pressure variation. The variable time step method can get a better result. What more, it is only after the variable time step method can be predicted without singularity. So the variable time step method is batter than the constant time step method in saving computational and keeping accuracy. This paper provides a new idea to solve Rayleigh-Plesset equation.关键词
