Extensional rheometry of mobile fluids. Part II: Comparison between the uniaxial, planar and biaxial extensional rheology of dilute polymer solutions using numerically-optimized stagnation point microfluidic devices
Simon J. Haward, Stylianos Varchanis, Gareth H. McKinley +2
In Part I of this paper [Haward et al. submitted (2023)], we presented a new three-dimensional microfluidic device (the optimized uniaxial and biaxial extensional rheometer, OUBER)…
Extensional rheometry of mobile fluids. Part I: OUBER, an optimized uniaxial and biaxial extensional rheometer
Simon J. Haward, Francisco Pimenta, Stylianos Varchanis +4
We present a numerical optimization of a "6-arm cross-slot" device, yielding several three-dimensional shapes of fluidic channels designed to impose close approximations to ideal u…
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…
