“…The developed model was successfully validated for a one-dimensional Stephan problem with different density ratio up to 1:1000, and the ability of the model to simulate two-dimensional droplet evaporation was tested. Begmohammadi et al [27] employed the phase-change model of Safari et al [26] to simulate nucleate pool boiling. Bubble growth on and departure from superheated surface was simulated.…”

“…the bubble growth and departure from superheated surface for liquid vapor density ratio up to 1000. Their results [9] reveal that the bubble departure diameter decreases as the density ratio increases while the bubble release period shows the opposite trend. Sadeghi et al [10] proposed a 3-D LBM for the simulations of pool boiling with high liquid-vapor density ratio, which was based on the Lee's method [8].…”

“…Based on the pseudo-potential model [3], Gong and Cheng [4] developed an improved two-phase lattice Boltzmann model, which was used to simulate the phase change in pool boiling for two dimensions [5,6] and three dimensions [7]. Using the LBM proposed by Lee [8], Begmohammadi et al [9] presented a numerical study on S278 THERMAL SCIENCE: Year 2020, Vol. 24, Suppl.…”

In this work a two-phase lattice Boltzmann method was used to numerically study the behavior of liquid-vapor phase change induced by a heated plate under the action of shearing. The effects of the action of shearing on the bubble growth and departure were investigated in terms of the flow features, the average heat flux and the bubble releasing period. It is shown that the shear flow significantly enhances the heat transfer of the system in two respects: increasing the average heat flux and decreasing the bubble releasing period. The effects of the intensity of the shear flow and the gravity force on the bubble releasing period were examined as well. The most striking finding is that there exists a sudden jump in the period at a critical shear intensity of the flow. The reason behind this abnormal behavior is that the residual part of bubble is nearly condensed after the bulk of bubble departs from the heated plate.

“…The developed model was validated successfully by Safari for simulation of two‐dimensional droplet evaporation. Begmohammadi et al used the phase‐change model of Safari to simulate nucleate pool boiling, and Hatani et al applied this model to investigate the vapor condensation, liquid film formation, and dewdrop sprinkling from a cryogenic horizontal tube. In these studies, the modified curved boundary treatment of Filippova and Hänel (FH) was used and the results were successfully validated by previous correlations.…”

Complex heat and mass transfers through falling‐film or spray‐film evaporation are widely used in chemical, refrigeration, petroleum refining, desalination, and food industries. Considering that microscopic effects, like surface tension, flow, mass, and heat transfers, are interdependent phenomena, the high‐precision simulation of falling‐film evaporation through a mesoscopic method is of great importance. In the current study, the lattice‐Boltzmann method and the phase‐field model with a proper source term are used for evaporation simulation in a horizontal‐tube falling film. Here, the curvature of the tube is captured by appropriate boundary conditions. Nondimensional numbers and the geometry of the model are determined in a range of practical values. By comparing the film thickness, mass, and heat transfer with valid references in the literature, an acceptable agreement is observed, which reveals the effectiveness of this method in understanding the details and predictions. Overall, the time evolution of temperature contours and streamlines during falling‐film evaporation approves the superiority of this method in keeping details along with lower difficulty and cost compared with the classical methods.
