Investigation of Combined Heat and Mass Transfer from a Wet Heat Exchanger. Part 2. Experimental Results and Operational Characteristics of Heat Exchangers in Dry/Wet Operations

摘要

This second part of a two-part paper summarizes the experimental evaluation of a plate finned heat exchanger both with and without the surface wetted by a flowing film of water. The results indicate an increase in heat transfer during wet operation of two to five times over that of dry operation for the same meteorological conditions. The deluge model is shown to accurately predict the wet performance using an experimentally determined deluge film coefficient and the dry performance characteristics. (ERA citation 08:044432)
