Modeling the dynamic thermal behavior of cooling towers containing packingmaterials

In this study, a mathematical model is presented to describe the dynamic th ermal behavior of counterflow cooling towers that contain packing materials . The proposed model takes into account both the sensible and latent hear c ooling effects on the tower performance. Closed-form solutions are obtained for the transient and steady temperature distribution within the cooling t ower Under steady-state conditions, a mathematical criterion is derived to obtain the proper length of the cooling tower that is sufficient to ensure complete cooling for the hot water stream.
