Abstract
This chapter introduces a one-step simplified lattice Boltzmann method (NOSLBM) for simulating multiphase flows with large density ratios and complex interfaces. Firstly, the basic equations of the original model of the lattice Boltzmann method (LBM), including moment conditions for the distribution functions, are presented. Then we briefly derive the NOSLBM using the Chapman-Enskog expansion to analyze the general evolution equation of the LBM. And several numerical examples are displayed, such as spinodal decomposition, bubble rising, and droplet splashing.
