MICROCHANNEL COMBUSTOR EVAPORATOR THERMAL-PROCESSES/

This article presents the results of an experimental investigation of the performance of an integrated microchannel combustor/evaporator. Se parate experimental investigations were conducted on combustion in sma ll channels and evaporation in microchannels. These results, along wit h the results of a simulation of heat transfer from the flue gas in mi crochannels, were used to design, and subsequently fabricate and test, microchannel combustor/evaporators. Performance results showed that t he combustor/evaporator was capable of achieving high heat flares (up to 30 W/cm(2)) while maintaining a high combustor efficiency.
