(406e) Experimental Studies on Lateral Expansion of A Biological Polymer Disk

Cellular foam structures are finding diverse application in various industries. Foaming occurs due to the rapid generation and expansion of gas cells or bubbles inside the liquid mass, resulting in a porous structure with desirable structural properties like density and texture. Numerous studies have been done to understand and model the growth of bubbles [1]. However, these studies are frequently inconvenienced by the lack of suitable methods to capture the phenomena as it happens inside the mass of expanding liquid. In this paper, the lateral expansion of a liquid mass is studied through a previously developed method [2] under varying conditions of blowing agent concentration, surface friction, pressure profile and axial mass transfer.
