A Lattice Boltzmann Equation for Waves
✍ Yan Guangwu πŸ“‚ Article πŸ“… 2000 πŸ› Elsevier Science 🌐 English βš– 91 KB

We propose a lattice Boltzmann model for the wave equation. Using a lattice Boltzmann equation and the Chapman-Enskog expansion, we get 1D and 2D wave equations with truncation error of order two. The numerical tests show the method can be used to simulate the wave motions.
