Evgeniy Boyko

Congratulations to Zuckerman Israeli Postdoctoral Scholar (Alum) Evgeniy Boyko, Head of the Technion Complex Fluids Lab at the Faculty of Mechanical Engineering, on the publication of a study in Physical Review Fluids. The Together with his research team, Dr. Boyko developed a theoretical model for slow (creeping) flow of an Oldroyd B viscoelastic fluid through gently varying contraction expansion channels (constrictions).

Abstract:
Flows of viscoelastic fluids in narrow non-uniform geometries, such as contraction, expansion, and contraction-expansion configurations, are ubiquitous in various engineering applications and physiological flow systems. For such flows, one of the key interests lies in understanding how fluid viscoelasticity affects the dependence of the pressure drop on the flow rate, which remains not fully understood compared to Newtonian flows.
