| 英文摘要 | In this paper, a general propagation lattice Boltzmann model for variable-coefficient non-isospectral Korteweg-de Vries (vc-nKdV) equation, which can describe the interfacial waves in a two layer liquid and Alfven waves in a collisionless plasma, is proposed by selecting appropriate equilibrium distribution function and adding the compensate function. The Chapman-Enskog analysis shows that the vc-nKdV equation can be recovered correctly from the present model. Numerical simulation for the non-propagating one soliton of this equation in different situations is conducted as validation. It is found that the numerical results match well with the analytical solutions, which demonstrates that the current general propagation lattice Boltzmann model is a satisfactory and efficient method, and could be more stable and accurate than the standard lattice Bhatnagar-Gross-Krook model.
