A two-dimensional numerical study of the stick-slip extrusion instability
(2007)
The time-dependent, compressible extrusion of a Carreau fluid is solved over the reservoir-die-extrudate region using finite elements in space and a fully implicit scheme in time. A nonmonotonic slip law based on experimental ...
Comparison of spectral and finite element methods applied to the study of the core-annular flow in an undulating tube
(2002)
A Galerkin/finite element and a pseudo-spectral method, in conjunction with the primitive (velocity-pressure) and streamfunction-vorticity formulations, are tested for solving the two-phase flow in a tube, which has a ...
On the combined effects of slip, compressibility, and inertia on the Newtonian extrudate-swell flow problem
(2013)
We solve both the planar and axisymmetric extrudate-swell flows of a compressible Newtonian liquid with Navier slip at the wall, using the finite-element method in space and a fully-implicit finite-difference scheme in ...
Development lengths in Newtonian Poiseuille flows with wall slip
(2016)
The effect of wall slip on the development of planar and axisymmetric Newtonian Poiseuille flows is studied by means of finite element simulations. The Navier slip law is employed. i.e., it is assumed that the slip velocity ...
