Abstract: A new lattice Boltzmann model is proposed for treating Euler equations. The numerical example shows that it can be used to simulate shock wave and contact discontinuity. The results are comparable with those obtained by traditional methods.

Key words: lattice Boltzmann method, Euler equations, 2 speed 3 entropy level model, stability
