WebFeb 9, 2024 · The cumulant lattice Boltzmann method (LBM) has been recently used to simulate multiphase-multicomponent flows by applying an external force. Furthermore, the mass and momentum are not conserved when an external force is used. In the classical approach, the third-order derivatives in density necessitate information from a large … WebLattice Boltzmann Methods (LBM) are a class of computational fluid dynamics (CFD) algorithms for simulation. Unlike traditional formulations that simulate fluid dynamics on a macroscopic level with a mesh, the LBM characterizes the problem on a
