Combined effects of compressibility and slip in flows of a Herschel-Bulkley fluid
(2013)In this work, the combined effects of compressibility and slip in Poiseuille flows of Herschel-Bulkley fluids are investigated. The density is assumed to obey a linear equation of state, and wall slip is assumed to follow ...

Development of confined viscoplastic flows with heterogeneous wall slip
(National Technical University of Athens, 2016)The steady, pressure-driven flow of a Herschel-Bulkley fluid in a channel is considered assuming that slip occurs on one wall only due to slip heterogeneities. Hence, the velocity profile is allowed to be asymmetric. The ...

Newtonian Poiseuille flows with slip and non-zero slip yield stress
(2013)The Newtonian Poiseuille flow is considered for various geometries, under the assumption that wall slip occurs above a critical value of the wall shear stress known as, the slip yield stress. In the axisymmetric and planar ...

Numerical study of the combined effects of inertia, slip, and compressibility in extrusion of yield stress fluids
(2014)The axisymmetric extrudate swell flow of a compressible Herschel–Bulkley fluid with wall slip is solved numerically. The Papanastasiou-regularized version of the constitutive equation is employed, together with a linear ...

Slip yield stress effects in start-up Newtonian Poiseuille flows
(2013)Analytical solutions are derived for various start-up Newtonian Poiseuille flows assuming that slip at the wall occurs when the wall shear stress exceeds a critical value, known as the slip yield stress. Two distinct regimes ...

Start-up and cessation Newtonian Poiseuille and Couette flows with dynamic wall slip
(2015)Analytical solutions are derived for the start-up and cessation Newtonian Poiseuille and Couette flows with wall slip obeying a dynamic slip model. This slip equation allows for a relaxation time in the development of wall ...

Viscoplastic flow development in a channel with slip along one wall
(2017)The flow development of a Herschel–Bulkley fluid in a horizontal channel is considered assuming that slip occurs only on the upper wall due to slip heterogeneities. Hence, the velocity profile is allowed to be asymmetric ...
