Stability and finite element approximation of phase change models for natural convection in porous media
(2019-11)In this paper we study a phase change problem for non-isothermal incompressible viscous flows. The underlying continuum is modelled as a viscous Newtonian fluid where the change of phase is either encoded in the viscosity ... -
Stability of a second-order method for phase change in porous media flow
(2018)We analyse the stability of a second-order finite element scheme for the primal formulation of a Brinkman-Boussinesq model where the solidification process influences the drag and the viscosity. The problem is written in ... -
Twofold Saddle-Point Formulation of Biot Poroelasticity with Stress-Dependent Diffusion
(2023)We present a new stress/total-pressure formulation for poroelasticity that incorporates the coupling with steady nonlinear diffusion modified by stress. This nonlinear problem is written in mixed-primal form, which combines ... -
Velocity‑vorticity‑pressure formulation for the Oseen problem with variable viscosity
(2021)We propose and analyse an augmented mixed finite element method for the Oseen equations written in terms of velocity, vorticity, and pressure with non-constant viscosity and homogeneous Dirichlet boundary condition for the ... -
Well-posedness and discrete analysis for advection-diffusion-reaction in poroelastic media
(2021)We analyse a PDE system modelling poromechanical processes (formulated in mixed form using the solid deformation, fluid pressure, and total pressure) interacting with diffusing and reacting solutes in the medium. We ...
