Rayleigh-Plesset simulation

Hi all,
I am in the process of modelling some microbubble-microchannel acoustic behaviour.
During this process, I am trying to check (before going into massive files) that the gas (air) bubble follows the Ideal Gas Law as well as its radial expansion follows the Rayleigh-Plesset equation. Although coming accross several tutorials about how to introduce the internal pressure (as pressure inside bubble will change with wall deformation, so pv^gamma = cte), and also checking the Ideal Gas checkbox in the Fluid properties of the pressure domain, this doesn't seem to be actually working.
I've been doing some research for a few weeks now and I can't find anyone able to do this. Has anyone tried to run some similar problem? If so,any success? Any recommendations or suggestions?
Thanks,
GVB
