“…A computational cell having temperature over T SH can be given a VOF fraction of the embryo. Although T SH may have the spatial variation on the heated surface according to the experiment, 10) T SH is assumed to be uniform on the heated surface, i.e., a nucleation site density is not considered in the present study.…”

This study focuses on the clarification of the heat transfer characteristics of the subcooled pool boiling, the discussion on its mechanism, and the establishment of a boiling and condensation model for direct numerical simulation on the subcooled pool boiling phenomena. In this paper, three dimensional numerical simulations based on the MARS (Multi-interface Advection and Reconstruction Solver) with a boiling and condensation model which consisted of the improved phase-change model and the relaxation time based on the quasi-thermal equilibrium state have been conducted for the bubble growth process in the subcooled pool boiling. The numerical results regarding the bubble growth process of the subcooled pool boiling show in good agreement with the experimental observation results and the existing analytical equations among Rayleigh, Plesset and Zwick and Mikic et al. Therefore, it was found that the improved boiling and condensation model with the relaxation time consideration can predict the bubble growth process of the subcooled pool boiling phenomena.

“…Ces résidus se comportent comme un germe d'une taille finie et ainsi ils facilitent la formation des bulles (germination hétérogène). Autrement dit, des bulles se forment plutôt dans les pores de l'anode que dans le bain [47,50,51,52,53,54,55,56]. Des pores qui contribuent à la production des bulles sont souvent appelés des sites actifs ou centres de formation.…”

“…Thanks to advances in technology, many new techniques, such as thermochromic liquid crystals (TLCs), MEMS, high-speed infrared cameras and so on, have been utilized for revealing the physics of nucleate pool boiling. Kenning and Yan (1996) and Kenning et al (2001) used thermochromic liquid crystals to study the temperature field at the backside of a 130 μm thick stainless steel plate. They studied the temperature imprint caused by the growth and detachment of a single vapour bubble by focusing on a single nucleation site during fully developed pool boiling.…”

Focusing on partial nucleate pool boiling at low heat flux, SOBER-SJ10, one of 27 experiments of the program SJ-10, has been proposed to study local convection and heat transfer around an isolated growing vapor bubble during nucleate pool boiling on a well characterized flat surface in microgravity. An integrated micro heater has been developed. By using a local pulse overheating method in the experimental mode of single bubble boiling, a bubble nucleus can be excited with accurate spatial and temporal positioning on the top-side of a quartz glass substrate with a thickness of 2 mm and an effective heating area of 4.5 mm in diameter, and then grows under an approximate constant heat input provided by the main heater on the back-side of the substrate. Ten thin film micro-RTDs are used for local temperature measurements on the heating surface underneath the growing bubble. Normal pool boiling experiments can also be carried out with step-by-step increase of heating voltage. A series of ground test of the flight module of SOBER-SJ10 have been conducted. Good agreement of the measured data of single phase natural convection with the common-used empirical correlation warrants reasonable confidence in the data. It is found that the values of the incipience superheat of pool boiling at different subcooling are consistent with each others, verifying that the influence of subcooling on boiling incipience can be neglected.
