Single bubble expansion equation

Hi,

I'm trying to solve the single bubble expansion equation numerically but my plots do not seems to be quite correct.

I would appreciate any idea.

Do you have expression in LaTeX form?

Try starting your bubble radius as 2*sigma/1.4, rather than 0.

Hi Mr. Stevens,

Thanks for your answer.

Do you have any idea how to plot the oscillation of the bubble, that is, to capture it's expansion and collapse as shown in this Wikipedia's figure ?

[Alan Stevens]

The Wikipedia picture notes that it uses a sinusoidal pressure difference. You have a fixed value.

Got it. thank you very much.
