Authors Dimakopoulos Y., Kelesidis G., Tsouka S., Georgiou G.C., Tsamopoulos J. Abstract BACKGROUND: In microcirculation, the non-Newtonian behavior of blood and the complexity of the microvessel network are responsible for the high flow resistance and the large reduction of the blood pressure. Red blood cell aggregation along with inward radial […]

Authors Fraggedakis D., Kouris C., Dimakopoulos Y., Tsamopoulos J. Abstract We study the flow of two immiscible, Newtonian fluids in a periodically constricted tube driven by a constant pressure gradient. Our volume-of-fluid algorithm is used to solve the governing equations. First, the code is validated by comparing its predictions to […]
Authors Pettas D., Karapetsas G., Dimakopoulos Y., Tsamopoulos J. Abstract It is well-known that by increasing the flow rate in polymer extrusion, the flow becomes unstable and the smooth extrudate surface becomes wavy and disordered to an increasing degree. In order to investigate the mechanisms responsible for these instabilities we […]
