Comparison of spectral and finite element methods applied to the study of the core-annular flow in an undulating tube
Kouris, C.; Dimakopoulos, Yannis; Georgiou, Georgios C.; Tsamopoulos, J. (2002)A Galerkin/finite element and a pseudo-spectral method, in conjunction with the primitive (velocity-pressure) and streamfunction-vorticity formulations, are tested for solving the two-phase flow in a tube, which has a ...

Hemodynamics in stenotic vessels of small diameter under steady state conditions: Effect of viscoelasticity and migration of red blood cells
Dimakopoulos, Yannis; Kelesidis, G.; Tsouka, S.; Georgiou, Georgios C.; Tsamopoulos, J. (2015)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 ...

Theoretical study of the flow in a fluid damper containing high viscosity silicone oil: Effects of shear-thinning and viscoelasticity
Syrakos, Alexandros; Dimakopoulos, Yannis; Tsamopoulos, John (2018)The flow inside a fluid damper where a piston reciprocates sinusoidally inside an outer casing containing high-viscosity silicone oil is simulated using a finite volume method, at various excitation frequencies. The oil ...

Viscoplastic flow in an extrusion damper
Syrakos, A.; Dimakopoulos, Yannis; Georgiou, Georgios C.; Tsamopoulos, J. (2016)Numerical simulations of the flow in an extrusion damper are performed using a finite volume method. The damper is assumed to consist of a shaft, with or without a spherical bulge, oscillating axially in a containing ...
