APPARATUS FOR PRECISE MEASUREMENTS OF POOL BOILING HEAT TRANSFER IN THE TEMPERATURE RANGE OF LIQUID NITROGEN.

Author(s) : BIER K., RUTHLEIN H.

Type of article: Article, IJR article

Summary

NEW APPARATUS FOR THE PRECISE MEASUREMENT OF POOL BOILING HEAT TRANSFER IN THE TEMPERATURE RANGE FROM ABOUT 70 K TO AMBIENT TEMPERATURE IS DESCRIBED. THE PERFORMANCE OF THIS APPARATUS HASBEEN PROVED BY SYSTEMATIC MEASUREMENTS WITH LIQUID NITROGEN AT SATURATION PRESSURES FROM 0.5 TO 30 BARS AND AT HEAT FLUX DENSITIES FROM 12 TO 85,000 W/M2. THE RELATIVE DEPENDENCE OF THE HEAT TRANSFER COEFFICIENT ON NORMALIZED SATURATION PRESSURE AND HEAT FLUX DENSITY IS THE SAME FOR NITROGEN AS FOR HIGHER BOILING REFRIGERANTS AND HYDROCARBONS.
