【摘要】We propose a method of higher moments on lattice Boltzmann equation for Tyson system to simulate chemical waves,Using Chapman-Enskog expansion and multiscale technique,we obtain a series of lattice Boltzmann equations in different time scales.We use the conservation law in time scale to and coefficients of macroscopic equations to find the equilibrium distribution function.The numerical examples show that this method can be used to simulate Tyson system with complex chemical waves.
