HEAT TRANSFER AT BOILING OF NITROGEN UNDER SUBATMOSPHERIC PRESSURE AND ITS INTENSIFICATION.

Author(s) : BELYAKOV V. P., ORLOV V. K.

Summary

MEASUREMENT OF HEAT EXCHANGE OF NITROGEN BOILING ON A TECHNOLOGICALSMOOTH SURFACE OF AN ALUMINIUM PIPE (16 MM DIAMETER, 100 MM LONG) AT FOUR DIFFERENT PRESSURES (0.098, 0.049, 0.016 AND 0.012 MEGAPASCALS. THE INTENSITY OF HEAT EXCHANGE REDUCES ABOUT 3 TIMES WHEN PRESSURE DROPS FROM ATMOSPHERIC TO A PRESSURE CLOSE TO THE TRIPLE POINT. THE CRYOSTAT USED FOR EXPERIMENT IS FURNISHED WITH SIGHT GLASSES FOR VISUAL OBSERVATION OF VAPORIZATION. THE EFFECT OF A CAPILLARY POROUS COATING OF THE ALUMINUUD THE MODEL APPLIED TO ANALYSE THIS LATTER CASE CONFIRMS THE EXPERIMENT AND DEMONSTRATES THAT THE APPLICATION OF A CAPILLARY POROUS COATING MAKES IT POSSIBLE TO INCREASE APPROXIMATELY 10-15 TIMES THE DENSITY OF THE HEAT FLUX AS COMPARED TO BOILING ON SMOOTH TECHNOLOGICAL SURFACE.
