| Abstract | The Lattice Boltzmann method, a molecule Kineticbased approach, is presented to solve fluid dynamics. Based on theory of turbulence and molecule kinetics, an extended Lattice Boltzmann equation is put forward to solve turbulent flow with high Reynolds number, in which turbulence sub-grid model is used to simulate vortex viscosity as well as turbulence relaxation time is introduced to modify the normal LBGK equation. The method to evaluate the turbulence relaxation time with particle distribution function is proposed combining with Smagorinsky turbulence model. Furthermore the extended Lattice Boltzmann method is applied to simulate the flows around square cylinder in the range of Reynolds number from Re=62 to Re= 9000. |
