The lattice Boltzmann method (LBM) is a computational fluid dynamics technique used for simulating complex fluid flow phenomena. It is based on the Boltzmann equation, which describes the statistical behavior of particles in a fluid system. In LBM, the fluid is divided into a lattice of grid points, and the distribution of particles at each point is modeled using a set of discrete velocity vectors. LBM allows for the simulation of fluid flow at a mesoscopic level, capturing phenomena such as turbulence, multiphase flow, and fluid-structure interactions. It is known for its scalability and ability to handle complex geometries with relatively simple boundary conditions. LBM is widely used in a variety of applications, including aerospace, automotive engineering, and biofluid dynamics. Overall, the lattice Boltzmann method is a powerful and efficient tool for studying fluid dynamics, providing insights into the behavior of fluids in a wide range of scenarios.
