Summary

NEWLY OBTAINED LOCAL HEAT TRANSFER DATA ARE PRESENTED FOR FLOW BOILING OF LIQUIDS IN 2 PARTIALLY HEATED VERTICAL CHANNELS WITH DIFFERENT OFFSET STRIP FIN GEOMETRIES OPERATING AT LOW TO MODERATE WALL SUPERHEAT LEVELS. DATA FOR WHICH NUCLEATE BOILING APPEARED TO BE COMPLETELY SUPPRESSED WERE ANALYZED TOGETHER WITH SIMILAR RESULTS FOR OTHER OFFSET FIN GEOMETRIES. FOR ALL GEOMETRIES CONSIDERED, THE DATA FOR ANNULAR FILM-FLOW EVAPORATION WERE FOUND TO CORRELATE WELL IN TERMS OF MODIFIED VERSIONS OF THE F AND MARTINELLI PARAMETERS USED BY BENNETT AND CHEN (1980) TO CORRELATE SIMILAR DATA FOR ROUND TUBES. FOR FIN MATRICES OF SIMILAR SIZE AND CONFIGURATION, THE FORCED CONVECTIVE COMPONENT OF THE TWO-PHASE HEAT TRANSFER COEFFICIENT WAS FOUND TO BE WELL REPRESENTED BY A SINGLE F-PARAMETER CORRELATION CURVE.
