Description

Abstract: 

Condensation heat transfer plays a vital role in various industrial applications. Surface condensers are one of the major components in thermal power systems where shell side condensation heat transfer on horizontal tubes is of key importance. Filmwise condensation is the dominating mode in most of the condensers. Extensive work has been performed on filmwise free and forced convection condensation heat transfer on horizontal tubes. This talk will present progress on condensation heat transfer on geometrically enhanced horizontal tubes. Adding integral-fins or pin-fins or wire wrapping around the tube, enhances available area for heat transfer, however, this also augments the condensate to retain on part of the tube. Therefore, for various condensing fluids, mechanism of condensation on enhanced tubes needs to be understood well for better and efficient heat transfer. Available models to predict condensate retention and heat transfer will be discussed as well. Finally, other enhanced heat transfer mechanics based upon the surface tension effects of fluids will be presented on horizontal single and bank of tubes.
