Perturbation solutions of weakly compressible Newtonian Poiseuille flows with Navier slip at the wall
(2012)
We consider both the planar and axisymmetric steady, laminar Poiseuille flows of a weakly compressible Newtonian fluid assuming that slip occurs along the wall following Navier's slip equation and that the density obeys a ...
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 second-order. A linear equation of state is assumed and a ...
Weakly compressible Poiseuille flows of a Herschel-Bulkley fluid
(2009)
In this work, we derive approximate semi-analytical solutions of the steady, creeping, weakly compressible plane and axisymmetric Poiseuille flows of a Herschel-Bulkley fluid. Since the flow is weakly compressible, the ...
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 ...
Stopping times in cessation flows of Bingham plastics with slip at the wall
(2012)
We solve numerically the cessation of axisymmetric Poiseuille flow of a Bingham plastic assuming that slip occurs along the wall. A power-law expression is used to relate the wall shear stress to the slip velocity. The ...
