| In this paper, the macro equation N-S equation which is corresponding to theLBGK equation was given, and all of this was from LB equation. And several surfacetracking methods and boundary conditions were introduced.In order to testify LB method, one of the basic two-dimensional models (D2Q9model) was used to simulate Poisson's flow with different relaxation time. And flowsimulation results and experience value was accordant to each other, and the accuracywas greatly affected by the relaxation time. At the same time, the level set method wasapplied in laminar flow with bubbles , the VOF method was applied to simulate uniformflow field and the rotating flow field with free interface. And the shape of the movementinterface remained unchanged.Finally, the recolor method was used to simulate the half-full pipe flow and the flowsimulation result and the experience value were corresponding. This paper madefoundation for further research. |
