Mean-Field-Scaling in Lattice Boltzmann Fluid Mixtures

June 1, 1999
Author(s)
Nicos Martys, Jack F. Douglas
Basic equilibrium properties of Lattice Boltzmann (LB) fluid mixtures (coexistence curve, surface tension, and interfacial profile) are calculated to characterize the critical phenomena occurring in these model liquids and to establish a reduced variable

Thermal Lattice Boltzmann Models (TLBM) for Compressible Flows

December 1, 1998
Author(s)
G Vahala, P Pavlo, L Vahala, Nicos Martys
The progress and challenges in thermal lattice Boltzmann modeling are discussed. In particular, momentum and energy closures schemes are contrasted. Higher order symmetric (but no longer space filling) velocity lattices are constructed for both 2D and 3D

Evaluation of the External Force Term in the Discrete Boltzmann Equation

November 1, 1998
Author(s)
Nicos Martys, X Shan, H Chen
A representation of the forcing term in the Boltzmann equation based on Hermite expansion of the Boltzmann distribution function in velocity phase space is derived. Based on this description of the forcing term, a systematic comparison of previous Lattice
