EFFECTIVE METHOD TO DECREASE VISCOSITY IN LATTICE BOLTZMANN EQUATION
降低格子Boltzmann方程沾滞系数的有效方法

It is pointed out that if collision term in lattice Boltzmann equation is changed from Fermi type to Boltzmann type, viscosity coefficient will be decreased greatly. Low viscosity makes lattice Boltzmann equation method more effecient in simulating fluid behaviors. Theoretical solution is coherent with simulation results.
