Extrusion of a compressible Newtonian fluid with periodic inflow and slip at the wall
(1996)We explore a mechanism of extrusion instability, based on the combination of nonlinear slip and compressibility. We consider the time-dependent compressible Newtonian extrudate swell problem with slip at the wall. Steady-state ...

Time-dependent plane Poiseuille flow of a Johnson-Segalman fluid
(1999)We numerically solve the time-dependent planar Poiseuille flow of a Johnson-Segalman fluid with added Newtonian viscosity. We consider the case where the shear stress/shear rate curve exhibits a maximum and a minimum at ...
