Pseudopotential Lattice Boltzmann Method for boiling heat transfer: A mesh refinement procedure

Boiling is a complex phenomenon where different non-linear physical interactions take place and for which the quantitative modeling of mechanism involved not fully developed yet. In last years, many works have been published focusing on numerical analysis this problem. However, lack assessing quantitatively sensitivity these simulations to grid parameters can be identified, especially Lattice Boltzmann method (LBM). The main goal work propose mesh refinement methodology simulating phase-change heat transfer problems employing pseudopotential LBM. This was based relating their lattice counterparts an arbitrary under viscous regime (where ?t??x2). A suitable modification EOS parameters, adjusting thermodynamic consistency surface tension certain ?x were steps proposed methodology. first ensemble simple including droplet vaporization Stefan performed validate assess influence some mechanisms. Global norms in space time used evaluate variations both density temperature fields pool boiling when discretization refined. It observed that provides convergent results all considered, convergence orders depend complexity simulated phenomena.
