Asymptotic solutions of weakly compressible Newtonian Poiseuille flows with pressuredependent viscosity
(2015)We consider both the axisymmetric and planar steadystate Poiseuille flows of weakly compressible Newtonian fluids, under the assumption that both the density and the shear viscosity vary linearly with pressure. The primary ...

Article
Compressible viscous flow in slits with slip at the wall
(1994)We study the timedependent 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 ...

Article
New analytical solutions for weakly compressible Newtonian Poiseuille flows with pressuredependent viscosity
(2016)Steadystate, isothermal, Poiseuille flows in straight channels and circular tubes of weakly compressible Newtonian fluids are considered. The major assumption is that both the mass density and the shear viscosity of the ...

Article
On numerical simulations of polymer extrusion instabilities
(2002)The objective of this study is mainly to review recent work concerning the numerical modeling of the stickslip and gross melt fracture polymer extrusion instabilities. Three different mechanisms of instability are discussed: ...

Article
Perturbation solution of the compressible annular Poiseuille flow of a viscous fluid
(2010)The isothermal annular Poiseuille flow of a weakly compressible Newtonian liquid with constant shear and bulk viscosities is considered. A linear equation of state is assumed and a perturbation analysis in terms of the ...

Article
Perturbation solutions of Poiseuille flows of weakly compressible Newtonian liquids
(2009)Both the planar and axisymmetric isothermal Poiseuille flows of weakly compressible Newtonian liquids with constant shear and bulk viscosities are solved up to the secondorder. A linear equation of state is assumed and a ...

Article
Timedependent compressible extrudateswell problem with slip at the wall
(1994)We solve the timedependent compressible Newtonian extrudateswell problem with slip at the wall, in an attempt to simulate the stickslip extrusion instability. An arbitrary nonlinear slip model relating the shear stress ...
