Mechanistic models for pool nucleate boiling heat transfer: input and validation

Steps towards the development of an experimentally verified simulation of pool nucleate boiling on a silicon wafer with artificial sites

“…Mukherjee and Dhir (2004), Dhir (2006), and have a minimum spatial resolution that is usually larger than the radius of typical nucleation sites. Hybrid mechanistic simulations, reviewed by Kenning et al (2006), replace the accurate simulation of events in the fluid region by simplified physical models, correlations and networking rules, e.g. for site activation, bubble growth and departure, seeding of unstable sites and local heat transfer.…”

“…The validation of a multi-site model against experimental data for boiling on metal surfaces is difficult because there are few sufficiently detailed data sets to provide input information about site positions and characteristics in addition to data to test the model, and because the potentially chaotic nature of boiling (Nelson et al, 1996, Mosdorf and requires statistical methods, Kenning et al (2006). These issues were explored by comparing the Ljubljana model with liquid crystal measurements of the spatio-temporal temperature fields on the back of a thin stainless steel plate during the boiling of water, Golobič et al (2004), during which bubbles were detected by computerised image analysis at 1505 locations, most of which were concentrated in 16 dense clusters.…”
