Optimal approximation spaces for discontinuous Petrov-Galerkin finite element methods
Ankit Chakraborty, Ajay Rangarajan, Georg May
Certain Petrov-Galerkin schemes are inherently stable formulations of variational problems on a given mesh. This stability is primarily obtained by computing an optimal test basis…
How to build coarse-grain transport models consistent from the kinetic to fluid regimes
Erik Torres, Georgios Bellas-Chatzigeorgis, Thierry E. Magin
In this paper, we examine how to build coarse-grain transport models consistently from the kinetic to fluid regimes. The internal energy of the gas particles is described through a…
A surrogate-based optimal likelihood function for the Bayesian calibration of catalytic recombination in atmospheric entry protection materials
Anabel del Val, Olivier P. Le Maître, Olivier Chazot +2
This work deals with the inference of catalytic recombination parameters from plasma wind tunnel experiments for reusable thermal protection materials. One of the critical factors…
Collisionless ion modeling in Hall thrusters: analytical axial velocity distribution function and heat flux closures
Stefano Boccelli, Thomas Charoi, Alejandro Alvarez-Laguna +3
The genesis of the ion axial velocity distribution function (VDF) is analyzed for collisionless Hall thruster discharges. An analytical form for the VDF is obtained from the Vlasov…
Dynamics of the Jet Wiping Process via Integral Models
M. A. Mendez, A. Gosset, B. Scheid +2
The jet wiping process is a cost-effective coating technique that uses impinging gas jets to control the thickness of a liquid layer dragged along a moving strip. This process is f…
Mutation++: MUlticomponent Thermodynamic And Transport properties for IONized gases in C++
James B. Scoggins, Vincent Leroy, Georgios Bellas-Chatzigeorgis +2
The Mutation++ library provides accurate and efficient computation of physicochemical properties associated with partially ionized gases in various degrees of thermal nonequilibriu…
