Résumé

Results showed the three-dimensional enhanced tube had the highest condensation heat transfer coefficient of any tube tested during the course of the study. Bundle average heat transfer coefficients for the three-dimensional tube showed a steady decline with increased heat flux and the row-by-row heat transfer coefficients showed an almost linear decrease with increased row number. The performance of the two-dimensional tube showed variations with heat flux but showed less sensitivity to inundation level. The experimental results for all tubes were compared with published correlations. Experimental results for the two-dimensional tube were predicted well by the correlations, but no suitable correlation was found for the three-dimensional tube so one was developed (see this Bulletin, reference 2006-1697).
