Theory of the lattice boltzmann method
WebbThe generalized lattice Boltzmann equation is constructed in moment space rather than in discrete velocity space. The generalized hydrodynamics of the model is obtained by solving the dispersion equation of the linearized LBE either analytically by using perturbation technique or numerically. WebbLattice Boltmzann method (LBM) has been developed as an important technique of computational fluid mechanics. Two-dimensional turbulent flow around NACA0012 airfoil, with Re=105 and AOA=4 (angle of attack), …
