Title
Fate of a gas cap hosted on a small surface during suspension foaming
Abstract: In this talk a hypothesis developed for accounting the transient volumetric change of a gas cap nucleated on a small surface during foaming a particulate suspension will be discussed. The hypothesis is based on a conjecture and attempts a continuum approach at colloidal length scales. A coarse testing of this hypothesis against the broad experimental observation of heterogeneous bubble generation during foaming viscoelastic medium with small dispersed particles will be presented. Its technological relevance to polymeric nanocomposite foaming will also be discussed.Bio-data: G. Harikrishnan is currently a faculty member of the department of Chemical Engineering at Indian Institute of Technology Kharagpur. His current research activity focuses on foams and polymer nanocomposites.
