Shift-periodic boundary condition for heat transfer computations in lattice Boltzmann method

摘要: Abstract With the developments in computational techniques, detailed simulations of flow thermomechanics and other phenomena complex geometries, such as granular or porous media, are attracting increasing interest. Recently, lattice Boltzmann method (LBM) is more often applied for computations. In this work, we present a novel numerical scheme shift-periodic boundary conditions internal energy distribution function thermal LBM. As validation cases, consider past an array heated obstacles regular random arrangements, akin to media geometry. The quality proposed documented LBM results presented temperature profiles. here also interest volume-averaged modeling heat transfer.
