Abstract
Viscoelastic materials share properties of an elastic solid at short response
times, and that of a viscous fluid at long times. They can be characterized by
long intrinsic relaxation times that separate the two behaviors.
While the spreading behavior of droplets on earth is mostly dominated by
gravitational forces, the spreading behavior of droplets in microgravity is the
result of an intricate balance between hydrostatic pressure, surface tension,
yield stress, and the effect of shear thinning.
In the talk, I present both numerical simulations and analytical calculations regarding spreading viscoelastic droplets in microgravity.
