Modelling Cavitation Bubble Radius Oscillation using Equation Based Modelling
Hello, I am trying to model the radius, R(t), oscillation of a cavitation bubble in liquid (compressible) subjected to alternating pressure at ultrasonic frequency. I would like to model the radius oscillation using the Gilmore model equation as shown in the attached .jpeg file.
The link to the published paper is as follows: link.springer.com/content/pdf/10.1007%2Fs11661-012-1188-3
I have tried to model equation (2) through the ODE module and by specifying the derivative of H by d(H,R), and managed to get the model running. However, the result seems to be very different from the results for the change in the bubble radius, R(t), presented in the paper.
Kind regards,
Charles
