A gallery of maximum-entropy distributions: 14 and 21 moments
Stefano Boccelli, Fabien Giroux, James G. McDonald
This work explores the different shapes that can be realized by the one-particle velocity distribution functions (VDFs) associated with the fourth-order maximum-entropy moment meth…
Numerical simulation of rarefied supersonic flows using a fourth-order maximum-entropy moment method with interpolative closure
Stefano Boccelli, Willem Kaufmann, Thierry E. Magin +1
Maximum-entropy moment methods allow for the modelling of gases from the continuum regime to strongly rarefied conditions. The development of approximated solutions to the entropy…
Modelling high-Mach-number rarefied crossflows past a flat plate using the maximum-entropy moment method
Stefano Boccelli, Pietro Parodi, Thierry E. Magin +1
The 10 and 14-moment maximum-entropy methods are applied to the study of high-Mach-number non-reacting crossflows past a flat plate at large degrees of rarefaction. The moment solu…
Realizability conditions for relativistic gases with a non-zero heat flux
Stefano Boccelli, James G. McDonald
This work introduces a limitation on the minimum value that can be assumed by the energy of a relativistic gas in the presence of a non-zero heat flux. Such a limitation arises fro…
14-moment maximum-entropy modelling of collisionless ions for Hall thruster discharges
Stefano Boccelli, James G. McDonald, Thierry E. Magin
Ions in Hall effect thrusters are often characterized by a low collisionality. In the presence of acceleration fields and azimuthal electric field waves, this results in strong dev…
Numerical investigation of reversed gas feed configurations for Hall thrusters
Stefano Boccelli, Thierry E. Magin, Aldo Frezzotti
A reversed gas feed configuration for Hall thrusters is proposed and studied numerically. As an alternative to standard direct injection, we investigate the effect of injecting the…
