Numerical Study of Single Bubble Growth on and Departure from a Horizontal Superheated Wall by Three-dimensional Lattice Boltzmann Method

Abstract

A three-dimensional hybrid lattice Boltzmann method was used to simulate the progress of a single bubble's growth and departure from a horizontal superheated wall. The evolutionary process of the bubble shapes and also the temperature fields during pool nucleate boiling were obtained and the influence of the gravitational acceleration on the bubble departure diameter (BDD), the bubble release frequency (BRF) and the heat flux on the superheated wall was analyzed. The simulation results obtained by the present three-dimensional numerical studies demonstrate that the BDD is proportional to g −0.301 , the BRF is proportional to g −0.58 , and the averaged wall heat flux is proportional to g 0.201 , where g is the gravitational acceleration. These results are in good agreement with the common-used experimental correlations, indicating the rationality of the present numerical model and results.

Mesoscopic characterization of bubble dynamics in subcooled flow boiling following a pseudopotential-based approach

“…Following the pioneering attempt of Rothman and Keller 35 , several multiphase-LB algorithms have been proposed, and the pseudopotential-based approach, originally formulated by Shan and Chen 36,37 , has found particular favour from the boiling community, as can be substantiated through the large volume of available literature [38][39][40][41][42][43][44][45] . It employs a nearestneighbor interaction model, which is a close approximate to the Lennard-Jones potential, allowing efficient computation and relatively-smooth representation of the interface.…”

Analysis of entropy generation minimization in flow of Ree-Eyring nanofluid between two coaxially rotating disks

“…Ijaz et al [7] scrutinized cubic autocataltic chemically reactive flow of non-Newtonian liquid (Casson fluid). Feng et al [8] studied single bubble growth on and departure from a superheated wall using Lattice Boltzmann method. Hayat et al [9] considered flow of silver and copper nanomaterials with entropy optimization over a stretchable surface.…”

Numerical investigation on bubble dynamics during pool nucleate boiling in presence of a non-uniform electric field by LBM

“…In recent decades, LBM has already been adopted to investigate the multiphase flow phenomena containing liquid-vapor phase change. Based on the phase-field LB method, many numerical simulations [19][20][21][22][23][24] were performed to study the bubble dynamics and heat transfer during pool boiling. For example, using three-dimensional (3D) LB model, the saturated nucleate boiling and film boiling were simulated and the influence of wall superheat and gravitational acceleration on bubble dynamics and heat transfer during nucleate boiling and film boiling were studied by Sadeghi et al [21,22].…”
