A mechanistic model for nucleate pool boiling including the effect of bubble coalescence on area fractions

Computer vision-assisted investigation of boiling heat transfer on segmented nanowires with vertical wettability

“…Here, the autonomous curation of massive in situ bubble datasets enabled by our framework stands to compliment recent advances in imaging techniques, that exclusively study top- and bottom-view bubble statistics to identify the fundamental physics governing pool boiling. 58,59,66,67 The datasets acquired at the ONB confirmed the correlations between bubble statistics and heat transfer performances. Due to the multidimensionality of the problem, innate structural heterogeneity of the hybrid NWs, and intrinsic variability of pool boiling experiments, still it is challenging to precisely predict overall HTC and CHF.…”

“…According to mechanistic pool boiling models, [53][54][55][56][57][58][59][60][61] D b , f b , and N b , are key parameters used to partition the heat flux into natural convection q″ nc , evaporation q″ ev , and bubble departure-driven forced convection q″ fc heat transfer modes, see ESI section S3.2. and eqn (S13)-(S16).…”

Bubble Growth on a Smooth Metallic Surface at Atmospheric and Sub-Atmospheric Pressure

“…34 r 0 . 69 (20) The above discussion proved that the bubble in Fig. (10) grows in the first 4 ms due to complete evaporation of the microlayer.…”

“…Some researchers such as Yabuki and Nakabeppu [33] measured the local temperature and heat flux underneath the growing bubble and gave an empirical expression for the initial microlayer thickness, see Eq. (20) . The radius predicted using this method ( Eq.…”

CNN-based visual analysis to study local boiling characteristics

“…Nowadays, in the literature on boiling process a special attention is paid to its local characteristics, such as the bubble departure diameters, the bubble growth rate, the nucleation site density and the frequency of nucleation. This interest relates to the fact that these characteristics are directly associated with the heat transfer rate and the development of crisis phenomena [1,2]. To study the local boiling characteristics a high-speed video recording is used most often [3][4][5][6][7].…”
