Abstract
We present a new lattice-Boltzmann method for hydrodynamic simulations , which is capable of handling very large density and temperature grad ients. Unlike other LBGK models, the discrete velocities we used cente r at the local mean Bow velocity, and their values vary according to t he local temperature. The adiabatic index of the gas can be easily con trolled by a parameter.
