A unification of least-squares and Green-Gauss gradients under a common projection-based gradient reconstruction framework
Alexandros Syrakos, Oliver Oxtoby, Eugene de Villiers +3
We propose a family of gradient reconstruction schemes based on the solution of over-determined systems by orthogonal or oblique projections. In the case of orthogonal projections,…
A family of first-order accurate gradient schemes for finite volume methods
Oliver Oxtoby, Alexandros Syrakos, Eugene de Villiers +3
A new discretisation scheme for the gradient operator, suitable for use in second-order accurate Finite Volume Methods (FVMs), is proposed. The derivation of this scheme, which we…
Oscillations of small bubbles and medium yielding in elastoviscoplastic fluids
Marco De Corato, Brice Saint-Michel, George Makrigiorgios +3
We investigate the radial oscillations of small gas bubbles trapped in yield-stress fluid and driven by an acoustic pressure field. We model the rheological behavior of the yield-s…
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.…
Theoretical study of the flow in a fluid damper containing high viscosity silicone oil: effects of shear-thinning and viscoelasticity
Alexandros Syrakos, Yannis Dimakopoulos, John Tsamopoulos
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…
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,…
