Solution of viscoplastic flows with the finite volume / multigrid method
(National Technical University of Athens, 2013)
We investigate the performance of the finite volume method in solving viscoplastic flows. The square lid-driven cavity flow of a Bingham plastic is chosen as the test case and the constitutive equation is regularised as ...
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 ...
The singular function boundary integral method for Laplacian problems with boundary singularities in two and three-dimensions
(2010)
We present a Singular Function Boundary Integral Method (SFBIM) for solving elliptic problems with a boundary singularity. In this method the solution is approximated by the leading terms of the asymptotic solution expansion, ...
Stopping times in cessation flows of Bingham plastics with slip at the wall
(2012)
We solve numerically the cessation of axisymmetric Poiseuille flow of a Bingham plastic assuming that slip occurs along the wall. A power-law expression is used to relate the wall shear stress to the slip velocity. The ...
