Abstrakt

An assessment of several promising techniques which use surface tension forces to enhance film condensation heat transfer on horizontal tubes is made. Recent progress on integral-fin tubes is stressed, including experimental findings on fin spacing, geometry and material, and the latest theoretical developments to predict performance. Condensation heat transfer enhancement on wire-wrapped tubes is also examined, as well as the use of non-wetting strips and porous drainage devices. The effect of condensate inundation on plain and enhanced tubes is briefly reviewed, and future research directions are discussed.
