Growth of Microcellular Foams in Viscoelastic Mediums
Keyword(s):
The growing of the critical bubble by diffusion process in visco-elastic medium was treated by an integral method for the concentration boundary layer. In this study, we obtained a set of the first order time dependent equations to obtain bubble radius and gas pressure inside the bubble simultaneously. The calculated final cell sizes depending on the initial saturation pressure are in close agreement with the observed ones. The governing equations developed in this study may be used in polymer processing of microcellular foams.
