One dimensional high-order moment models with realistic collisions for nonequilibrium ion transport in weakly ionized plasmas
Anatole Berger, Alejandro Alvarez Laguna
Ion-neutral collisions are fundamental in the transport of partially ionized plasmas. When collisional scales are comparable to the system scales or the electric field is strong, n…
Numerical challenges in the simulation of 1D bounded low-temperature plasmas with charge separation in various collisional regimes
Louis Reboul, Marc Massot, Alejandro Alvarez Laguna
We study a 1D geometry of a plasma confined between two conducting floating walls with applications to laboratory plasmas. These plasmas are characterized by a quasi-neutral bulk t…
An asymptotic preserving well-balanced scheme for the isothermal fluid equations in low-temperature plasma applications
Alejandro Alvarez Laguna, Teddy Pichard, Thierry Magin +3
We present a novel numerical scheme for the efficient and accurate solution of the isothermal two-fluid (electron and ion) equations coupled to Poisson's equation for low-temperatu…
Consistent transport properties in multicomponent two-temperature magnetized plasmas:
Alejandro Alvarez Laguna, Quentin Wargnier, A. Laguna +4
A fluid model is developed for multicomponent two-temperature magnetized plasmas in chemical non-equilibrium from the partially- to fully-ionized collisional regimes. We focus on t…
A GPU-enabled implicit Finite Volume solver for the ideal two-fluid plasma model on unstructured grids
Isaac Alonso Asensio, Alejandro Alvarez Laguna, Mohamed Hassanine Aissa +3
This paper describes the main features of a pioneering unsteady solver for simulating ideal two-fluid plasmas on unstructured grids, taking profit of GPGPU (General-purpose computi…
Multifluid modeling of magnetosonic wave propagation in the solar chromosphere -- effects of impact ionization and radiative recombination
Yana G. Maneva, Alejandro A. Laguna, Andrea Lani +1
In order to study chromospheric magnetosonic wave propagation including, for the first time, the effects of ion-neutral interactions in the partially ionized solar chromosphere, we…
