Author(s) : JENSEN M. K., BERGLES A. E.

Type of article: Article

Summary

A STUDY OF BOILING R113 IN ELECTRICALLY HEATED COILS OF VARIOUS DIAMETERS IS REPORTED. SUBCOOLED CRITICAL HEAT FLUX (CHF) IS LOWER WITH COILS THAN WITH STRAIGHT TUBES. THE DIFFERENCE INCREASES AS MASS VELOCITY AND RATIO OF TUBE DIAMETER TO COIL DIAMETER (D/D) INCREASES. ON THE CONTRARY, QUALITY CHF IS ENHANCED AND INCREASES WITH D/D; CHF INITIALLY INCREASES WITH INCREASING MASS VELOCITY, BUT DECREASES AFTER A MAXIMUM IS REACHED.
