The Lattice Boltzmann Method (LBM) is a computational fluid dynamics technique used to simulate fluid flow. It models fluid behavior by representing particles on a discrete lattice grid, where each particle moves and interacts according to specific rules. This approach simplifies complex fluid dynamics problems, making it easier to analyze various flow scenarios. LBM is particularly useful for studying complex systems, such as those involving turbulence or multiphase flows. It has applications in fields like engineering, meteorology, and biophysics, allowing researchers to gain insights into fluid behavior in both natural and industrial processes.
