Numerical schemes for a multi-species quantum BGK model

Gi-Chan Bae, Marlies Pirner, Sandra Warnecke

This work is devoted to the numerical implementation of the quantum Bhatnagar- Gross-Krook (BGK) model for gas mixtures consisting of classical and quantum particles (fermions, bos…

A review on a general multi-species BGK model: modelling, theory and numerics

Marlies Pirner, Sandra Warnecke

In this article we focus on kinetic equations for gas mixtures since in applications one often has to deal with mixtures instead of a single gas. In particular we consider an appro…

Numerical schemes for a multi-species BGK model with velocity-dependent collision frequency

Jeffrey Haack, Cory Hauck, Christian Klingenberg +2

We consider a kinetic description of a multi-species gas mixture modeled with Bhatnagar-Gross-Krook (BGK) collision operators, in which the collision frequency varies not only in t…

A consistent BGK model with velocity-dependent collision frequency for gas mixtures

Jeff Haack, Cory Hauck, Christian Klingenberg +2

We derive a multi-species BGK model with velocity-dependent collision frequency for a non-reactive, multi-component gas mixture. The model is derived by minimizing a weighted entro…

Using the Navier-Cauchy equation for motion estimation in dynamic imaging

B. N. Hahn, M. -L. Kienle-Garrido, C. Klingenberg +1

Tomographic image reconstruction is well understood if the specimen being studied is stationary during data acquisition. However, if this specimen changes during the measuring proc…
