Role of interfacial dynamics on the hydrodynamic features of systems exhibiting large interfacial areas under dynamic conditions
Our Guest Speaker: Dr. Omer ATASI, FNRS Research fellow, TIPs department, Université libre de Bruxelles (ULB)
Abstract
In a climate of increasing anthropic pressure on ecosystems and increasing concerns about global warming, increasing the energy efficiency of processes is crucial. Processes involving mass transfer using dispersed multiphasic systems are ubiquitous in the pharmaceutical, coating, and food industries. Increasing the mass transfer performance of these systems goes through controlling their stability and tailoring the fluid flow near interfaces to mix the diffusion layers. This has the potential to reduce the energy requirement of many unit operations. However, this requires understanding the fine interplay between interfacial rheology, the flows near interfaces, the hydrodynamic coupling between interfacial flows and larger-scale bulk flows, and the resulting mass transfer. In this talk I will show, using and developing innovative simulation strategies, how interfacial flows induced by capillarity and surface tension gradients affect the hydrodynamic features of systems exhibiting large interfacial areas under dynamic conditions.
Biography
The Omer Atasi’s scientific interests lie in the fields of fluid mechanics and transfer phenomena, with a particular focus on dispersed flows. He is currently working in the TIPs department of the Université libre de Bruxelles (ULB) as a research fellow (FNRS) developing new multi-scale Direct Numerical Simulation methods for multiphase flows. He obtained my PhDs from two institutions, namely the Université libre de Bruxelles (2014-2018), and the Institut de Mécanique des Fluides de Toulouse (IMFT) (2015-2018) in the field of fluid dynamics. During his research career, he worked on various multiphase systems such as bubble dynamics in surfactant solutions at IMFT, evaporation of complex solutions at Laboratoire de Génie Chimique (LGC) and thin film dynamics at Université Libre de Bruxelles and Princeton University. His research activities have been rewarded on three occasions by the "Léopold Escande", "Jean Nougaro" and "Van Buuren Jaumottee-Demoulin" awards.
