Research Update: Boiling on Enhanced Surfaces
This webinar reviews improvements in boiling heat transfer through the use of passive surface enhancements. Commercial tubes enhanced with porous coatings or mechanically with integral structure provide a larger surface area for heat transfer and nucleation site density when compared with plain tubes. Boiling heat transfer enhancement for clean fluids increases as the heat flux, pressure, and boiling range of mixtures decrease. This review identifies recent studies of commercially relevant surfaces and presents models and correlations that may ultimately improve performance prediction in software such as Xchanger Suite.
