In this research, the corresponding mathematic model was established firstly, thereafter, a splitting-approach was applied to achieve the component equations. In the process of solving equations, a semi-Lagrangian method was used to solve both transient and convection terms, and to solve the pressure equation for incompressible fluid the bound-based projection algorithm was adopt. This study only realized the numerical simulation for a simple cube space. Simulation results are displayed by OpengGL programming in terms of three-dimensional flow field and the distribution of Smoke-Dust concentrations. The stable and fast solution can be achieved by using the method we proposed.
