AN EXPERIMENTAL STUDY OF THE TEMPERATURE DISTRIBUTION IN A HORIZONTAL R12 EVAPORATOR FITTED WITH TWISTED TAPES.
Author(s) : AGRAWAL K. N., VARMA H. K., LAL S.
Summary
THE PAPER DESCRIBES THE EXPERIMENTS MEASUREMENTS OF SWIRL FLOW BOILING INSIDE A HORIZONTAL TUBE. FOUR STAINLESS STEEL TWISTED TAPES WERE USED. THE EXISTENCE OF AN ANNULAR FLOW PATTERN AND AN INSTABILITY OF THE LIQUID FILM INSIDE THE TUBE WAS ESTABLISHED. THE NATURE OF THE LIQUID FILM AT THE WALL DEPENDS ON THE COMBINATION OF HEAT FLUX, MASS VELOCITY, TWIST RATIO AND VAPOR QUALITY VALUES. LOWER TWIST RATIOS WERE FOUND TO YIELD BETTER UNIFORMITY OF TEMPERATURES.
