Abstract

Entropy generation is an effective tool in energy process analysis and  optimization. Problems as entropy generation in heat exchangers due to pressure  losses and due to hut transfer are discussed. The entropy generation number Ns  provide, a meaning for evaluating the performance of a heat exchanger.  
The performance of in-line tube bank are studied at constant relative transfer  pitch with variable relative longitudinal pitch and vice-versa. The results of the  performance showed that there is a minimum entropy generation occurs at  particular Reynolds number and number of transfer units for each tube bank.
