Bi-Conductive Surfaces for Boiling Enhancement
PAGE TITLEOverviewPAGE SUMMARY We report the counterintuitive mechanism of increasing boiling heat transfer by incorporating low-conductivity materials at the interface between the surface and fluid. By embedding an array of non-conductive lines into a high-conductivity substrate, in-plane variations in the local surface temperature are created. During...
