We study the motion of a viscous drop rising in a viscoelastic liquid that exhibits elastic and
shear thinning effects and is represented by the exponential PTT constitutive model. We …

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 …

We present predictions for the flow of elastoviscoplastic (EVP) fluids in the 4 to 1 planar
contraction geometry. The Saramito-Herschel-Bulkley fluid model is solved via the finite …

A numerical code for the simulation of liquid metal magnetohydrodynamic (MHD) flow in
breeding blankets of future fusion reactors has been extended to address complex MHD …

A new and simple implicit Green-Gauss gradient (IGG) scheme for unstructured meshes is
proposed exploiting the ideas from the linearity-preserving U-MUSCL scheme to define …

The least squares and Green–Gauss gradient schemes have been traditionally studied as
two distinct techniques for gradient computation on unstructured meshes in the literature. In …

In this research, the comparison of force calculation methods in magnetostatic simulations
within a cell-centered finite volume framework is presented. Various procedures for …

In unstructured mesh solvers based on the finite volume method, accurate gradient
calculation is crucial for determining the accuracy of equations. However, most mainstream …

The present work primarily focuses on the study of three gradient reconstruction techniques
applied to the calculation of viscous terms in a cell-centered, finite volume formulation for …

We present a generic framework for gradient reconstruction schemes on unstructured
meshes using the notion of a dyadic sum-vector product. The proposed formulation …
