Summary

THE PAPER STUDIES ENHANCEMENT OF HEAT AND MASS TRANSFER BETWEEN A COUNTERCURRENT, GRAVITY-DRAINED WATER FILM AND AIR FLOWING IN A VERTICAL TUBE. HEAT TRANSFER CORRELATIONS FOR TURBULENT, SINGLE-PHASE HEAT TRANSFER IN PIPES HAVING WALL-ATTACHED SPACED RIBS ARE USED TO SELECT THE PREFERRED WIRE DIAMETER, AND TO PREDICT THE GAS PHASE HEAT AND MASS TRANSFER COEFFICIENTS. THE AUTHORS HYPOTHESIZE THAT THE BEST HEAT/MASS TRANSFER AND FRICTION PERFORMANCE WILL BE OBTAINED WITH THE ROUGHNESS AT THE SURFACE OF THE WATER FILM. THE MEASURED HEAT/MASS TRANSFER ENHANCEMENT AGREED VERY CLOSELY WITH THE PREDICTED VALUES.
