Lattice-Boltzmann-based two-phase thermal model for simulating phase change

Abstract: A lattice Boltzmann (LB) method is presented for solving the energy conservation equation in two phases when the phase change effects are included in the model. This approach employs multiple distribution functions, one for a pseudotemperature scalar variable and the rest for the various species. A nonideal equation of state (EOS) is introduced by using a pseudopotential LB model. The evolution equation for the pseudotemperature variable is constructed in such a manner that in the continuum limit one recovers … Show more

“…Some authors have suggested similar approaches for the correction term Gj [23,28]; however, we employ different considerations for the thermal conductivity. The dimensionless thermal conductivity is denoted as K with the reference value given by PcCp x 8 2 J 8 , [45], where cp is the specific heat at constant pressure. The thermal diffusivity is therefore defined as a = K /(prCp.r), while a LB = (r?…”

“…In the Pseudopotential (PP) LB model, introduced by Shan and Chen, adding molecular interactions between particle distributions at the meso‐scale can simulate spontaneous phase separation. Many researchers embarked on this concept with the view of describing two‐phase systems, also in our research group . As multiple interfaces do not need to be tracked, captured and/or reconstructed, the PP‐LB method is computationally very attractive …”

“…To alleviate the weaknesses of the original Shan-Chen model, several improvements [6][7][8][9][10][11] have been carried out. For phase-change heat transfer, the thermal pseudopotential LB model is developed by devising the temperature distribution function [12][13][14][15][16]. The temperature distribution function is used to solve the macroscopic energy equation.…”
