"Simulation of viscoelastic flow"
Viscoelastic fluids are complex fluids that possess memory. Their dynamics
depends on the history of the flow. Such fluids are very common in
biological systems (e.g., blood) and in industrial applications (e.g.,
plastics) and there is an urging need to understand their flow
properties. The formidable complexity of their equations of motion prevents
any analytical treatment therefore the need to develop numerical methods
for simulating such flows. Despite over two decades of extensive efforts
very little has been achieved so far. In this talk I will present an
overview of the subject, and introduce a new methodology applicable for
such problems. Results will be shown through a classical application where
the fluid is confined between two cylinders and its motion is driven by
This exciting lecture will include a short video show.
Coffee, cookies, and company will be available
at 3:45 pm in room 12 of the mathematics building.
As usual, we will meet with the speaker for an
"after colloquium coffee chat" in Beit-Belgia,
for yet more coffee and better pastry.
