THEORETICAL MODEL OF ENHANCING CONDENSATION HEAT TRANSFER FOR CRYOGENIC FIELD ON A V-TYPE FLUTED SURFACE.

Author(s) : LIN L.

Summary

THE PAPER DEALS WITH THE THEORETICAL MODEL OF CONDENSATION HEAT TRANSFER OF CRYOGENIC FLUID ON A V-TYPE VERTICAL FLUTED SURFACE. CONDENSATION PROCESS OF SATURATED VAPOUR ON A GROOVE OF FLUTED SURFACE CAN BE DIVIDED INTO TWO PARTS IN THE ANALYSIS OF THIS THEORETICAL MODEL. THE FIRST PART IS THE DRAINAGE FLOW OF CONDENSATE WHICH MAINLY OCCURS IN THE THROUGH REGION OF A GROOVE. THE SECOND PART IS THE CONDENSATION OF SATURATED VAPOUR ON THE FLUTED SURFACE WHICH TAKES PLACE NEAR CREST REGION. THE CONDENSATION OF A VAPOUR NEAR THE CREST OF A GROOVE IS STUDIED WITH THE BASIC ASSUMPTIONS REQUIRED IN NUSSELT'S ANALYSIS. THE AVERAGE NUSSELT NUMBER FOR A GIVEN LENGTH OF THE TUBE IS COMPUTED BY SOLVING THE SURFACE TENSION-GOVERNED EQUATION OF MOTION.
