TY - JOUR TI - Numerical study on the boiling heat transfer induced by two heated plates AU - Shan Xiaopeng AU - Guan Geng AU - Nie Deming JN - Thermal Science PY - 2020 VL - 24 IS - 11 SP - 257 EP - 265 PT - Article AB - A two-phase lattice Boltzmann method was used to numerically study the boiling heat transfer related to the liquid-vapor transition induced by two heated plates. The effects of the gravity force as well as the separation between the heated plates were examined. The focus is on the bubble departure behavior resulting from the interaction between bubbles, which can be roughly classified into four types of pat­tern according to the separation between plates. In particular, it is shown that the bubble merging may take place twice in one cycle when the separation is close to a certain value. This is referred to as the pattern of alternation of bubble merging before and after departure, for which a sudden jump is seen in the bubble release period. Furthermore, the heat flux and the flow features are also shown to illustrate the behavior of heat transfer in the present system.
