Exergy Analysis Of Cross Flow Shell and Tube Condenser

Heat exchangers are of considerable importance, and widely used in various types of applications, therefore the design of heat exchangers continues to be a centrally important issue in energy conservation. To determine the optimal design and operational conditions of heat exchangers, the performance of heat exchangers should be evaluated correctly, thus the usage of accurate and reliable performance evaluation methods is the key to the successful design and optimal use of heat exchangers. Reviews includes Energy and Exergy analysis of thermal Power Plant system based on advance thermodynamic topics Exergy analysis which is the combination of first law and second law of Thermodynamics and highlights inefficiencies of a system. In entire reviews the need for the systematic design of heat exchangers using a second law-based procedure is recalled and discussed, and then, second-law based performance evaluation criteria for heat exchangers are presented. These criteria have been grouped into two classes: the criteria that use entropy as evaluation parameter and the criteria that use exergy as evaluation parameter. They present the entropy as an evaluation parameter in the following forms Entropy generation rate; Entropy generation number; Augmentation entropy generation number; Heat exchange reversibility norm (HERN); Local entropy generation number, and also use of exergy as evaluation parameter in the forms of various analysis of operating conditions of the systems.
