A hierarchy of non-equilibrium two-phase flow models

G Linga, T Flåtten - ESAIM: Proceedings and Surveys, 2019 - esaim-proc.org
We review and extend a hierarchy of relaxation models for two-phase flow. The models are
derived from the non-equilibrium Baer–Nunziato model, which is endowed with relaxation …

A two-fluid model for vertical flow applied to CO2 injection wells

G Linga, H Lund - International Journal of Greenhouse Gas Control, 2016 - Elsevier
Flow of CO 2 in wells is associated with substantial variations in thermophysical properties
downhole, due to the coupled transient processes involved: complex flow patterns, density …

A two-fluid four-equation model with instantaneous thermodynamical equilibrium

A Morin, T Flåtten - ESAIM: Mathematical Modelling and Numerical …, 2016 - numdam.org
We consider an equilibrium version of a common two-fluid model for pipe flow, containing
one mixture mass equation and one mixture energy equation. This model can be derived …

[HTML][HTML] Two-phase nozzle flow and the subcharacteristic condition

G Linga, P Aursand, T Flåtten - Journal of Mathematical Analysis and …, 2015 - Elsevier
We consider nozzle flow models for two-phase flow with phase transfer. Such models are
based on energy considerations applied to the frozen and equilibrium limits of the …

Plane-wave analysis of a hyperbolic system of equations with relaxation in

MV de Hoop, JG Liu, PA Markowich… - arXiv preprint arXiv …, 2018 - arxiv.org
We consider a multi-dimensional scalar wave equation with memory corresponding to the
viscoelastic material described by a generalized Zener model. We deduce that this …
