Heat transfer characterization of plate fin-tube heat exchangers.

Author(s) : KAYANSAYAN N.

Type of article: Article, IJR article

Summary

The effects upon the performance of plate fin-tube cross flow heat exchangers due to outer surface geometry are considered. The finning parameter varying from 11 to 23, a total of 10 geometrically distinct configurations was tested over a Reynolds number range from 100 to 30,000. The tube outside diameter with the collar thickness defines the characteristic dimension. The convective heat transfer coefficients are presented as plots of Colburn j-factor versus Reynolds number and compare well with previous studies. The dispersion in the majority of data is more or less 10%. The j-factor, the Reynolds number and the finning parameter are correlated.
