Thixotropic flow past a cylinder
(2014)
We study the flow of a thixotropic fluid around a cylinder. The rheology of the fluid is described by means of a structural viscoplastic model based on the Bingham constitutive equation, regularised using the Papanastasiou ...
Solution of the square lid-driven cavity flow of a Bingham plastic using the finite volume method
(2013)
We investigate the performance of the finite volume method in solving viscoplastic flows. The creeping square lid-driven cavity flow of a Bingham plastic is chosen as the test case and the constitutive equation is regularised ...
Cessation of the lid-driven cavity flow of Newtonian and Bingham fluids
(2016)
We provide benchmark results for a transient variant of the lid-driven cavity problem, where the lid motion is suddenly stopped and the flow is left to decay under the action of viscosity. Results include Newtonian as well ...
Randomness switches the dynamics in a biophysical model for Parkinson Disease
(2012)
The interpallidal network of the two areas, the Globus Pallidus External (GPE) and the Subthalamic nucleus, (STN) plays an important role for controlling the movement. Changes in the dynamics of this network are closed ...
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 ...
The influence of temperature on rheological properties of blood mixtures with different volume expanders-implications in numerical arterial hemodynamics simulations
(2011)
During the complicated cardiac surgery on a non-beating heart with cardiopulmonary bypass, protection of the heart is accomplished by injecting cold cardioplegic solutions. In most forms of circulatory shock, it is necessary ...
The influence of oxygen concentration on the rheological properties and flow of whole human blood
(2016)
Variations in blood oxygen concentrations are not only part of the normal physiology but they may also indicate various pathological conditions. In the present work, we examined the influence of oxygen concentration on the ...
Tentative study of flow patterns in the North Aegean Sea using NOAA-AVHRR images and 2D model simulation
(1996)
A statistical technique for image processing, the maximum cross correlation (MCC) method, was utilized on sequences of NOAA-AVHRR thermal data in order to explore the surface advective current dynamics at the discharge ...
