Fundamental Conditions for N-th Order Accurate Lattice Boltzmann Models
Hudong Chen, Xiaowen Shan
In this paper, we theoretically prove a set of fundamental conditions pertaining discrete velocity sets and corresponding weights. These conditions provide sufficient conditions fo…

Discrete Rotational Symmetry, Moment Isotropy, and High Order Lattice Boltzmann Models
Hudong Chen, Isaac Goldhrish, Steven Orszag
Conventional lattice Boltzmann models only satisfy moment isotropy up to fourth order. In order to accurately describe improtant physical effects beyond the isothermal Navier-Stoke…
