Superheated mixtures of cyclohexane vapor and nitrogen and benzene vapor and nitrogen were passed at various flow rates downward through a vertical double pipe condenser with cooling water flawing counter-currently in an annular space.

The method of Colburn and Hougen for the design of cooler-condensers was used to compare predicted heat transfer area to the experimental heat transfer area. Based on the ay-stems investigated, limits of accuracy of the predicted heat transfer areas were set as a function of inlet and cutlet Reynolds numbers. A suggested modification of the Colburn-Hougen correlation was made to extend the limits of accuracy. It was also shown that within the described limits the accuracy of prediction is independent of point values of temperature and heat transferred along the heat exchanger and is primarily dependent on agreement of terminal conditions.
