Effective volumetric lattice Boltzmann scheme - art. no. 056705

An efficient fractional volumetric scheme is proposed for lattice Boltzmann method (LBM). By reducing the effective time step, the scheme possesses mu ch better stability particularly for thermal LBM. The same accuracy and sim plicity of the standard LBM are preserved for achieving the Navier-Stokes e quation. Since the effective viscosity is reduced by the fraction factor p, the scheme becomes very effective for simulating high Reynolds number ther mal flows.
