Compressible viscous flow in slits with slip at the wall
Georgiou, Georgios C.; Crochet, M. J. (1994)We study the time-dependent compressible flow of a Newtonian fluid in slits using an arbitrary nonlinear slip law relating the shear stress to the velocity at the wall. This slip law exhibits a maximum and a minimum and ...

Newtonian and non-Newtonian flow in a channel obstructed by an antisymmetric array of cylinders
Georgiou, Georgios C.; Momani, S.; Crochet, M. J.; Walters, K. (1991)Consideration is given to the flow of Newtonian and non-Newtonian elastic liquids in a channel obstructed by an antisymmetric array of cylinders. Experiments are carried out on Newtonian maltose-syrup/water mixtures and a ...

The simultaneous use of 4×4 and 2×2 bilinear stress elements for viscoelastic flows
Georgiou, Georgios C.; Crochet, M. J. (1993)Mixed finite elements for viscoelastic flows based on a 4×4 sub-linear interpolation for the extra stress components satisfy the Babuska-Brezzi condition and are highly stable. They have been proved to be quite satisfactory ...

The time-dependent extrudate-swell problem of an Oldroyd-B fluid with slip along the wall
Brasseur, E.; Fyrillas, Marios M.; Georgiou, Georgios C.; Crochet, M. J. (1998)We demonstrate that viscoelasticity combined with nonlinear slip acts as a storage of elastic energy generating oscillations of the pressure drop similar to those observed experimentally in extrusion instabilities. We ...
