RECENT PROGRESS IN ENHANCING FILM CONDENSATION HEAT TRANSFER ON HORIZONTAL TUBES
摘要
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.
