摘要

Experiments were carried out to study the heat transfer and pressure drop characteristics of convex louver fin tube heat exchangers. Totally, seven samples of heat exchangers, including five convex-louver, one wavy configuration and one plate fin configuration were tested in the present investigation. The effects of row number and fin pitch of the convex-louver were also investigated. Results are presented as plots of friction factor, f, and Colburn j factor against Reynolds number based on tube collar diameter in the range of 400 to 8000. The presenting data were also compared to the wavy and plain fin geometry. It is found that the fin pitch has negligible effect on the Colburn j factor, and the row effect is negligible with increasing Reynolds number.
