A revisit of the development of viscoplastic flow in pipes and channels
Alexandros Syrakos, Evgenios Gryparis, Georgios C. Georgiou
This study revisits the development of viscoplastic flow in pipes and channels, focusing on the flow of a Bingham plastic. Using finite element simulations and the Papanastasiou re…
Analytical solution of the Poiseuille flow of a De Kee viscoplastic fluid
Alexandros Syrakos, Aggelos Charalambous, Georgios C. Georgiou
We provide an explicit analytical solution of the planar Poiseuille flow of a viscoplastic fluid governed by the constitutive equation proposed by De Kee and Turcotte (Chem. Eng. C…
A finite volume method for the simulation of elastoviscoplastic flows and its application to the lid-driven cavity case
Alexandros Syrakos, Yannis Dimakopoulos, John Tsamopoulos
We propose a Finite Volume Method for the simulation of elastoviscoplastic flows, modelled after the extension to the Herschel-Bulkley model by Saramito [J. Non-Newton. Fluid Mech.…
Thixotropic flow past a cylinder
Alexandros Syrakos, Georgios C. Georgiou, Andreas N. Alexandrou
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 equ…
Viscoplastic flow in an extrusion damper
Alexandros Syrakos, Yannis Dimakopoulos, Georgios C. Georgiou +1
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,…
