Tamás)Pressure dependent viscosity in dense suspensionsTuesday, 13 October
2026, 10:00, KFKI Campus, Bldg. 1, 2nd floor, Conference RoomMixtures of
solid particles and a fluid are common in Nature and industry: sand on the
beach is just one example out of many. The mechanical and flow behavior of
suspensions contains a number of physics mysteries. We unravel some and
discover more mysteries by working with a model suspension, composed of soft,
slippery spheres suspended in water. We find that the flow behavior of these
suspensions can be set by the external pressure, much like Bridgman
discovered the pressure dependent viscosity of Newtonian liquids.
Additionally, the boundaries of these suspensions are curiously important in
determining its flowability. We will give an overview of recent experimental
results and introduce a model that couples the confinement sensitivity and
boundary effects. Minden érdeklődőt szívesen látunk! - Everyone is
welcome to attend.Tamás Pusztaisem-admin AT wigner.hun-ren.hu
