Type of article: Article

Summary

THE MODEL INCLUDES THE EFFECTS OF CONDENSATE FLOW AND HEAT TRANSFER ON THE FIN ROOT TUBE SURFACE IN THE UNFLOODED REGION OF THE TUBE, AND THE WALL TEMPERATURE VARIATION BETWEEN THE FIN ROOT AND THE FIN ROOT TUBE SURFACE. THE EXPRESSION FOR THE FLOODING ANGLE IS ALSO EXTENDED. IT IS SHOWN THAT THE MODEL CAN PREDICT THE AVERAGE HEAT TRANSFER COEFFICIENT SATISFACTORILY OVER A WIDE RANGE OF FIN SPACINGS. AN AGREEMENT OF WITHIN MORE OR LESS 20% IS FOUND BETWEEN THE PREDICTIONS AND MOST OF THE AVAILABLE EXPERIMENTAL DATA COVERING 12 FLUIDS AND 31 TUBES.
