Thermo-viscous instability of flow in a weakly heat-conducting channel
Federico Lanza, Gaute Linga, Fabian Barras +1
An instability may arise when a hot viscous fluid enters a thin gap and cools through heat transfer to a colder surrounding environment. Fluids whose viscosity increases strongly u…

Non-Newtonian rheology in a capillary tube with varying radius
Federico Lanza, Alex Hansen, Alberto Rosso +1
The flow through a capillary tube with non-constant radius and where bubbles of yield stress fluid are injected is strongly non-linear. In particular below a finite yield pressure…
