… We can adopt the physical interpretation that the relaxation time 6 is very long compared
with w_1. The second speed, the equilibrium speed of propagation, is defined as …

… with two-phase flow experiments in a small glass bead pack that even though transient features
of the fluid interfaces (like slowly relaxing … the relaxation time is much faster than the time …

… Furthermore, dynamical two-phase flow processes will generally not take place in thermodynamic
equilibrium. However, the relaxation time towards equilibrium may be small for several …

In this paper we propose a color-gradient lattice Boltzmann (LB) model for simulating two-phase
flows with high density ratio and high Reynolds number. The model applies a …

… to study the two-phase flow. Compared with previous multiple-relaxation-time multiphase
models, this model is stable and accurate for the simulation of a two-phase flow in a much …

… of these relaxation processes, we consider the limits of zero and infinite relaxation times. By
… of the mixture sound velocity for the thermally relaxed model. This allows us to directly prove …

… As the relaxation time ε of the relaxation system (1.1) goes to zero, we expect the solutions
to approach the solutions of the equilibrium system (1.5). This was rigorously justified by Yong …

… relaxation terms into momentum and energy relaxation equations. These relaxation terms
… Then, after taking the singular limit when the characteristic relaxation time goes to zero, one …

… relaxation time entropic realization of a two-phase flow lattice … While the original model with
a single relaxation time allows … Here we show that the entropic multiple relaxation time model …

… schemes (relaxing and relaxed) to a certain two-phase model … We first demonstrate that the
original relaxation schemes of … transition from two-phase flow to single-phase flow. However, …
