摘要：
The entropic lattice Boltzmann (LB) method has recently been extended to include energy conservation in order to simulate weakly compressible flows. One of the limitations of this method when using the BGK collision model is the fixed Prandtl number. In this paper a new simple method is proposed and validated in order to simulate fluids of arbitrary Prandtl number.
