摘要

Two-dimensional incompressible stratified flows are simulated by the two-component lattice Boltzmann method. The red and blue particles are miscible and the gravity acts on the blue particles only. The density fractuation is expressed by the ratio of the density of the blue particles and the total density. The Boussinesq equation is derived and the total density is confirmed not to vary much. The blocking and the selective withdrawal phenomena are successively simulated.
