Transient vaporization experiments were conducted to determine the usefulness of conductive-film heaters in boiling experiments and the qualitative functional relation between surface temperature and time during boiling. Discussions are given of results on the influence of liquid conductivity on the performance of conductive films, the visual characteristlcs of heat transfer from conductive films, and temperature measurements on conductive films. Graphical representations are given of the results for the electrical heat- generation rate, and relative change, in electrical resistance as functions of pulse time. A series of concentric heat-transfer and pressure-drop experiments was completed using a nickel heater tube. The pressure-drop results are shown as friction factors as a function of Reynolds number with a standard curve for comparison. The concentric heat-transfer tests covered heat-generation rates to 500,000 Btu/hr-ft/sup 2/ and water velocities of 2 to 25 fps. (B.O.G.)
