Abstract
The link basis is introduced as an alternative to a polynomial collision basis. They coincide for one particular eigenvalue configuration, the two-relaxation-time (TRT) collision operator, suitable for both mass and momentum conservation laws. TRT operator is equivalent to the BGK collision in simplicity but the additional collision freedom relates it to multiple-relaxation-times (MRT) models. “Optimal convection” and “optimal diffusion” eigenvalue solutions for the TRT E-model allow to remove next order corrections to AADE. Numerical results confirm the Chapman-Enskog and dispersion analysis.
