NLS-Boussinesq方程的格子Boltzmann模型求解
Lattice Boltzmann Method for the NLS-Boussinesq Equation
摘要
Abstract
A lattice Boltzmann model with dual distribution functions is developed,and the evolution equa-tions in the model are Taylor expanded.The Chapman-Enskog multiscale expansion technique is com-bined to derive the equilibrium distribution functions and correction functions and then to recover the nonlinear coupled NLS-Boussinesq equations.关键词
