Advanced thermal lattice Boltzmann method for the simulation of latent heat thermal energy in a porous storage unit

The current research expounds numerical investigation of key parameters effects, namely porosity ( ε= 0.4, 0.6, 0.7 and 0.8), Reynolds number Re = 100, 200, 400 600) Eckert Ec 0, 1, 5 10) on the forced convective laminar flow heat transfer through a horizontal porous channel filled with metal foam structure impregnated paraffin as phase change material (PCM). Darcy-Brinkman-Forchheimer model under local thermal non-equilibrium (LTNE) condition is deemed at representative elementary volume (REV) scale. fully coupled equations Navier-Stokes, Poisson’s equation, energy equations, continuity equation were handled numerically via single relaxation time lattice Boltzmann method (TSRT-LBM). To facilitate implementation, all LB are based same speed discretization scheme (D2Q9). Three-population distribution functions applied to simulate fluid flow, temperatures solid phases. Previously, was validated by available cases. Then, comprehensive has been performed investigate influence aforementioned dimensionless numbers. All LBM results found be highly consistent other works. outcomes reported that lower porosities, exergy efficiencies increased increasing . However, for large values, optimum critical ~ 400. sum up, it can stated implemented demonstrated suitable approach study sensible storage.
