TLDR
In this paper, the effect of the Lewis factor on the performance prediction of natural draft and mechanical draft wet-cooling towers is investigated, where the authors show that the amount of water that evaporates, however, is a function of the actual value of Lewis factor.About:

An exergy analysis on the performance of a counterflow wet cooling tower
TL;DR: In this paper, an exergy analysis is used to indicate exergy and exergy destruction of water and air flowing through the cooling tower, and the results show that water exergy decreases continuously from top to bottom, while air exergy is expressed in terms of convective and evaporative heat transfer.

Air-cooled heat exchangers and cooling towers
TL;DR: The requirement for a small temperature difference between the exhaust steam and the atmosphere while rejecting large quantities of heat to air having a low heat capacity compared with water, poses a challenging technological problem which has resulted in a number of different engineering solutions.

Cooling tower performance evaluation: Merkel, Poppe, and e-NTU methods of analysis
J. C. Kloppers,Detlev G. Kröger +1 more
TL;DR: In this article, the effect of ambient humidity and temperature on the performance of cooling towers employing the Merkel, e-NTU, and Poppe methods of analysis is evaluated. And the importance of using a particular method of analysis when evaluating the performance characteristics of a certain fill material and subsequently employing the same analytical approach to predict cooling tower performance is stressed.
