- Title
On the moment system and a flexible Prandtl number.
- Authors
Machado, Raúl
- Abstract
The Maxwell-Boltzmann moment system can be seen as a particular case of a math-ematically more general moment system proposed by Machado.1 These last moments, of which a suggested continuous distribution and an integral generating form are pre-sented here for some orders, are used in this paper to theoretically show (one of) their usefulness: A flexible Prandtl number can be obtained in both the Boltzmann equa-tion and in the lattice Boltzmann equation with a conventional single relaxation time Bhatnagar-Gross-Krook (BGK) collision model.
