Abstract:

We used the lattice Boltzmann method to study the thermal wave equation and constructed a lattice Boltzmann model for the thermal wave
equation. By means of this model, the one and twodimensional thermal wave equations were simulated. Comparison between the result obtained by the lattice Boltzmann model and the result obtained by the classical method shows that this method can be used to simulate thermal wave problems.

Key words: lattice Boltzmann model, thermal wave equation, higherorder moments method
