Abstract

Abstract: A 5-Bit lattice lattice Boltzmann model is pr oposed for RLW equation.Using Chapman Enskog expansion and multiscale technique,it obt a ins the higher order moments of equilibrium distribution function,the 3rd dispers ion coefficients and 4th order viscosity.The parameters in this scheme can be de termined by analysis of the stability.

Key words: lattice Boltzmann method, RLW equations, multiscale method, 5-Bit lattice, conservation law on time scale t₀
