Lattice boltzmann method

WebLattice Boltzmann method is relatively new method in the field of computational fluid dynamics. It has been derived from lattice gas automata and is still under development. Basic steps of the LBM (collision, streaming, boundary conditions, macroscopic quantities) will be presented. Comparison with the finite difference method that uses Navier-Stokes … WebIn this study, we present a finite volume lattice Boltzmann method (LBM) for simulating fluid flows on curved surfaces in three-dimensional (3D) space. The curved surfaces are discretized using unstructured triangular meshes. We choose the D3Q19 lattice and the triangular meshes for the velocity and spatial discretizations, respectively.
