Pressure-driven flow of a Herschel-Bulkley fluid with pressure-dependent rheological parameters
(2018)
The lubrication flow of a Herschel-Bulkley fluid in a symmetric long channel of varying width, 2h(x), is modeled extending the approach proposed by Fusi et al. [“Pressure-driven lubrication flow of a Bingham fluid in a ...
Lubrication solution of the axisymmetric Poiseuille flow of a Bingham fluid with pressure-dependent rheological parameters
(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 ...
Analytical solution of the flow of a Newtonian fluid with pressure-dependent viscosity in a rectangular duct
(2018)
We derive a fully analytical solution for the steady flow of an isothermal Newtonian fluid with pressure-dependent viscosity in a rectangular duct. The analytical solution for the governing equations is exact (based on the ...
Axisymmetric Poiseuille flow of a Bingham plastic with rheological parameters varying linearly with pressure
(2018)
We consider the steady axisymmetric Poiseuille flow of a Bingham plastic under the assumption that both the plastic viscosity and the yield stress vary linearly with pressure. An analytical solution is derived for the case ...
Newtonian Poiseuille flow in ducts of annular-sector cross-sections with Navier slip
(2018)
We consider the Newtonian Poiseuille flow in a duct the cross section of which is either a circular or an annular sector assuming that Navier slip occurs either along both the cylindrical walls or only along the outer ...
Numerical and asymptotic solutions of axisymmetric Poiseuille flows of yield stress fluids with pressure-dependent rheological parameters
(GRACM, 2018)
The lubrication flow of a Bingham plastic in long tubes of varying radius 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 ...
Blue Energy Potential Analysis in the Mediterranean
(2019)
This paper describes the status of the potential of blue energy in the Mediterranean region, with focus on the region around Cyprus. Previous studies are reviewed, the main findings of the blue energy potential analysis ...
Lubrication solution of the flow of a Herschel-Bulkley fluid with pressure-dependent rheological parameters in an asymmetric channel
(2019)
The lubrication flow of a Herschel-Bulkley fluid in a long asymmetric channel, the walls of which are described by two arbitrary functions h1(x) and h2(x) such that h1(x) < h2(x) and h1(x) + h2(x) are linear, is solved ...
Determining true material constants of viscoplastic materials from rotational rheometer data
(2018)
We analyse the circular Couette flow of Herschel–Bulkley fluids to investigate the validity of the assumption that the rate of strain distributions across the gap share a common point. It is demonstrated that this is true ...
