Analytical solution of the flow of a Newtonian fluid with pressuredependent viscosity in a rectangular duct
Housiadas, Kostas D.; Georgiou, Georgios C. (2018)We derive a fully analytical solution for the steady flow of an isothermal Newtonian fluid with pressuredependent viscosity in a rectangular duct. The analytical solution for the governing equations is exact (based on the ...

Article
Asymptotic solutions of weakly compressible Newtonian Poiseuille flows with pressuredependent viscosity
Poyiadji, Stella; Housiadas, Kostas D.; Kaouri, Katerina; Georgiou, Georgios C. (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
Laminar axisymmetric flow of a weakly compressible viscoelastic fluid
Housiadas, Kostas D.; Georgiou, Georgios C.; Mamoutos, Ioannis G. (2012)The combined effects of weak compressibility and viscoelasticity in steady, isothermal, laminar axisymmetric Poiseuille flow are investigated. Viscoelasticity is taken into account by employing the OldroydB constitutive ...

Article
Lubrication solution of the axisymmetric Poiseuille flow of a Bingham fluid with pressuredependent rheological parameters
Housiadas, Kostas D.; Ioannou, Iasonas; Georgiou, Georgios C. (2018)The lubrication flow of a Bingham plastic in long tubes is modeled using the approach proposed by Fusi and Farina (Appl. Math. Comp. 320, 1–15 (2018)). Both the plastic viscosity and the yield stress are assumed to vary ...

Article
New analytical solutions for weakly compressible Newtonian Poiseuille flows with pressuredependent viscosity
Housiadas, Kostas D.; Georgiou, Georgios C. (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 ...

Newtonian Poiseuille flows with pressuredependent wall slip
Panaseti, Pandelitsa; Housiadas, Kostas D.; Georgiou, Georgios C. (2013)The effect of pressuredependent slip at the wall in steady, isothermal, incompressible Poiseuille flows of a Newtonian liquid is investigated. Exponential dependence of the slip coefficient on the pressure is assumed and ...

Article
A note on the unbounded creeping flow past a sphere for Newtonian fluids with pressuredependent viscosity
Housiadas, Kostas D.; Georgiou, Georgios C.; Tanner, R. I. (2015)We investigate theoretically isothermal, incompressible, creeping Newtonian flows past a sphere, under the assumption that the shear viscosity is pressuredependent, varying either linearly or exponentially with pressure. ...

Article
Perturbation solution of Poiseuille flow of a weakly compressible OldroydB fluid
Housiadas, Kostas D.; Georgiou, Georgios C. (2011)The isothermal, planar Poiseuille flow of a weakly compressible OldroydB fluid is considered under the assumption that the density of the fluid obeys a linear equation of state. A perturbation analysis for all the primary ...

Perturbation solutions of weakly compressible Newtonian Poiseuille flows with Navier slip at the wall
Poyiadji, Stella; Georgiou, Georgios C.; Kaouri, Katerina; Housiadas, Kostas D. (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 ...

Pressuredriven flow of a HerschelBulkley fluid with pressuredependent rheological parameters
Panaseti, Pandelitsa; Damianou, Yiolanda; Georgiou, Georgios C.; Housiadas, Kostas D. (2018)The lubrication flow of a HerschelBulkley fluid in a symmetric long channel of varying width, 2h(x), is modeled extending the approach proposed by Fusi et al. [“Pressuredriven lubrication flow of a Bingham fluid in a ...

Stability of the annular Poiseuille flow of a Newtonian liquid with slip along the walls
Chatzimina, Maria Evangelia; Georgiou, Georgios C.; Housiadas, Kostas D.; Hatzikiriakos, Savvas George (2008)The annular Poiseuille flow of a compressible Newtonian fluid is studied assuming that slip occurs along the wall. Different slip models relating the wall shear stress to the slip velocity are employed. In the case of ...

The steady annular extrusion of a Newtonian liquid under gravity and surface tension
Housiadas, Kostas D.; Georgiou, Georgios C.; Tsamopoulos, J. (2000)The steady extrusion of a Newtonian liquid through an annular die and its development outside and away from the die are studied under the influence of gravitational and surface tension forces. The finite element method ...
