Explore a 42-minute lecture examining the formation and evolution of interfacial patterns when Newtonian fluids displace soft glassy colloidal suspensions in radial Hele-Shaw geometry. Delve into how pattern morphology is influenced by the suspension's elasticity, displacing fluid flow rate, and fluid pair interfacial tension. Learn about the distinctive structural features of various pattern morphologies, quantified through areal ratios comparing developed pattern areas to their enclosing circles. Understand the spatio-temporal pattern growth analysis and its implications for pattern selection mechanisms, while discovering correlations between growth mechanisms and final morphologies. Gain insights into practical applications for controlling interfacial instabilities in mud and cement slurry displacement processes.
