摘要
Wfe formulate a new thennal lattice Boltzmann model to simulate compressible flows with a high Mach number.The main difference from the standard lattice Boltzmanii models is that the p&rticlc velocities are no longer a constantj varying with the mean velocity and internal energy.The proper heat conduction term in the energy equation is recovered by modiHcation of the fluctuating kinetic energy transported by particles.The simulation of Couette How is in good agreement with the analytical solutions.
