Interfacial Pattern Morphologies in Radial Displacement of Aging Viscoelastic Suspensions - Lecture 11

Explore the fascinating world of interfacial pattern formation in a lecture by Prof. Ranjini Bandyopadhyay from the Raman Research Institute in Bengaluru, India. Discover how the displacement of a soft glassy colloidal suspension by a Newtonian fluid in a radial Hele-Shaw geometry creates diverse pattern morphologies. Learn about the factors influencing these patterns, including the suspension's elasticity, fluid flow rate, and interfacial tension. Examine the unique structural features of different morphologies and how they can be distinguished using areal ratios. Delve into the spatio-temporal growth of these patterns and uncover important information about pattern selection mechanisms. Gain insights into the correlations between growth mechanisms and fully-developed morphologies. Understand the potential applications of this research in preventing and controlling interfacial instabilities in the displacement of mud and cement slurries.
