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,…
Performance of the finite volume method in solving regularised Bingham flows: inertia effects in the lid-driven cavity flow
Alexandros Syrakos, Georgios C. Georgiou, Andreas N. Alexandrou
We extend our recent work on the creeping flow of a Bingham fluid in a lid-driven cavity, to the study of inertial effects, using a finite volume method and the Papanastasiou regul…
Solution of the square lid-driven cavity flow of a Bingham plastic using the finite volume method
Alexandros Syrakos, Georgios C. Georgiou, Andreas N. Alexandrou
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…
A timestepper approach for the systematic bifurcation and stability analysis of polymer extrusion dynamics
M. E. Kavousanakis, L. Russo, C. I. Siettos +2
We discuss how matrix-free/timestepper algorithms can efficiently be used with dynamic non-Newtonian fluid mechanics simulators in performing systematic stability/bifurcation analy…
