Subsequently, we performed direct numerical simulations of viscosity-stratified two-layer plane Poiseuille flow employing a front-tracking/finite difference method (Cao et al.

Yih (1967) used a long-wave perturbation analysis to show that two-layer, viscosity-stratified plane Poiseuille flow and plane Couette flow can be unstable for arbitrarily small Reynolds numbers.

The time-dependent, incompressible, one-dimensional plane Poiseuille flow of an Oldroyd-B fluid with slip along the wall is studied using a non-monotonic slip equation relating the shear stress to the velocity at the wall.

We consider the time-dependent, incompressible, one-dimensional plane Poiseuille flow of an Oldroyd-B fluid.

Su and Khomami (12), using a modified Oldroyd-B fluid model and a pseudospectral formulation, investigated the effect of shear thinning viscosity and elasticity on the interfacial stability of superposed

plane Poiseuille flow of viscoelastic fluids.

Lee and White (12) studied the interfacial deformation of superposed plane poiseuille flow of polystyrene (PS) and high-density polyethylene (HDPE) and showed the existence of interfacial instabilities.

In an earlier study, we have experimentally determined the stability of superposed plane poiseuille flow of the PP/HDPE system at 204 [degrees] C (14).
