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 ...
Rheological effects of strusture breakdown in semisolid slurries
(2004)
An essential element for the integration of the semisolid metal (SSM) process in the production of complex commercial components is the availability of accurate mathematical and computational tools that could describe both ...
Stability of the annular Poiseuille flow of a Newtonian liquid with slip along the walls
(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 ...
Cessation flows of bingham plastics with slip at the wall
(National Technical University of Athens, 2013)
We use finite elements in space and a fully implicit scheme in time in order to solve the cessation of axisymmetric Poiseuille flow of a Bingham plastic under the assumption that slip occurs along the wall. The Papanastasiou ...
Steady flow of a two-dimensional film under pressure
(2000)
We use finite elements and the full Newton iteration method to solve the steady, two-dimensional flow of a Newtonian planar film, issuing from a slit under a pressure difference between the two free surfaces, in the presence ...
Design of a prototype tsunami warning and early response system for Cyprus - TWERC
(2010)
Described is the expansion of an existing and operational ocean observatory known as CYCOFOS (Cyprus Coastal Ocean Forecasting and Observing System), with a network of tsunami detection sensors. The expanded network will ...
Effect of posture change on the geometric features of the healthy carotid bifurcation
(2009)
Segmented cross sectional MRI images were used to construct 3D virtual models of the carotid bifurcation in 5 healthy volunteers. Geometric features such as bifurcation angle, planarity angle, asymmetry angle tortuosity ...
