Abstract

The relevant literature for flow boiling in microgaps is presented, with a focus on how the experimental conditions affect heat transfer and the fluid flow. Flow regimes in microgaps generally follow those seen at larger scales, though the validity of using the Taitel-Dukler map to predict the flow regime at a given experimental condition has not been proven. A comparison to heat transfer in microchannels is also provided. Experimental results of a systematic series of measurements are described for flow boiling of water in microgaps of several sizes and mass flux. Inlet flow to the heated surface is laminar and fully developed. Pressure drop and heat transfer coefficients are summarized graphically, and a correlation for the heat transfer coefficient is presented.

Nächstes Kapitel Flow Boiling of Dilute Emulsions in a Microgap

FC-77 is one of several Fluorinert™ fluids manufactured by 3M™, Inc., St. Paul, Minnesota. Fluorinert™ fluids are perfluorinated or fully fluorinated compounds, with all available carbon bond sites occupied by fluorine atoms. An example of a fully fluorinated compound is FC-72, whose chemical composition is C₆F₁₄. FC-77 is a perfluorinated compound whose chemical composition is C₈F₁₆O. Data are available for thermodynamic and transport properties of FC-77 at multimedia.3m.com/mws/media/64893O/fluorinert-electronic-liquid-fc-77.pdf

The Novec™ HFE fluids are produced by 3M™, Inc. as an alternative to their Fluorinert™ FC fluids. The Novec™ fluids are hydrofluoroethers (HFEs), which are segregated chains, with one perfluorinated part of the chain being separated via an oxygen atom, or ether, from a portion of the chain that is fully hydrogenated, with all carbon bond sites being occupied by hydrogen. The Novec™ fluids have a much lower global warming potential than the Fluorinert™ fluids. Novec 7200 and 7300 have chemical compositions of C₄F₉OC₂H₅ and C₇H₃F₁₃O, respectively. Their thermal and fluid transport properties can be obtained at https://www.3m.com/3M/en_US/novec-us/
