Bubble dissolution

There are many subtleties in adopting the reference frame (Brady, 1975a), some of which are discussed here so that the different forms of equations during crystal dissolution or growth and during bubble dissolution or growth can be understood.

The dissolved gas concentration at the bubble/melt interface, can be related to the bubble pressure P, through Henry s law. Gogos compared his model s predictions with the experimental data produced by Spence. The model predictions fit very well with experimental data when selecting a degree of saturation close to 100% (91.9-99.6%). An alternative approach has been proposed by Kontopoulou and Vlachopoulos, who modeled the dynamics of bubble dissolution into the melt using conservation of mass and momentum.f ... 

The densification process in rotational molding has been studied from both fundamental and practical perspectives. The models presented in the previous sections have furthered the understanding of the densification process in rotational molding however, their use has been limited to the prediction of the densification process carried out under isothermal conditions. It is well known that heat transfer, powder coalescence, bubble formation, and bubble dissolution are collectively important in rotational molding however, very few studies have addressed all aspects in modeling the densification process in rotational molding.

Taking the pulse off time at which SL disappeared, the resonance size of the cavitation bubbles was calculated. Epstein Plesset equation, (Eq. 1.3) which relates bubble dissolution time to its radius, was used for this purpose.
