Cessation of the lid-driven cavity flow of Newtonian and Bingham fluids
Syrakos, A.; Georgiou, Georgios C.; Alexandrou, Andreas N. (2016)We provide benchmark results for a transient variant of the lid-driven cavity problem, where the lid motion is suddenly stopped and the flow is left to decay under the action of viscosity. Results include Newtonian as well ...

Performance of the finite volume method in solving regularised Bingham flows: Inertia effects in the lid-driven cavity flow
Syrakos, A.; Georgiou, Georgios C.; Alexandrou, Andreas N. (2014)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 regularisation of the Bingham constitutive model ...

Solution of the square lid-driven cavity flow of a Bingham plastic using the finite volume method
Syrakos, A.; Georgiou, Georgios C.; Alexandrou, Andreas N. (2013)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 and the constitutive equation is regularised ...

Thixotropic flow past a cylinder
Syrakos, A.; Georgiou, Georgios C.; Alexandrou, Andreas N. (2014)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 equation, regularised using the Papanastasiou ...

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 ...
