Summary

AXIALLY VARYING VAPOUR SUPERHEATS IN CONVECTIVE FILM BOILING HAVE BEEN MEASURED FOR WATER FLOWING IN A VERTICAL TUBE AT LOW TO MODERATE PRESSURES AND MASS FLOW RATES. MEASUREMENTS OF WALL TEMPERATURE AND NONEQUILIBRIUM VAPOUR TEMPERATURE WERE OBTAINED AS FUNCTIONS OF DISTANCE FROM THE QUENCH FRONT. THE EXPERIMENTAL RESULTS INDICATE A ZONE NEAR THE QUENCH FRONT WHERE THE VAPOUR GENERATION RATE IS RELATIVELY HIGH, FOLLOWED BY A FAR ZONE WHERE THE GENERATION RATE DROPS OFF TO A RELATIVELY LOW MAGNITUDE. THE DATA OBTAINED AGREE WITH THE VERY LIMITED PREVIOUSLY REPORTED STEADY-STATE DATA.
