Several problems on the lattice Boltzmann method (Ⅰ)

The lattice gas method and the subsequent lattice Boltzmann method are new methods which are completely different from th traditional calculation of the flow field. Its development tendency and the impact on the traditional fluid mechanics were unexpected was hailed as a revolution in modern fluid mechanics. This paper mainly discusses the source of relevant thought and some key work in the development process of this field in order to give a review of these stirring years. Historically, five stages in the development of lattice Boltzmann methods can be distinguished. We follow the corresponding exciting development of both methods since 1989 and the men who have made contributions to this field.
