REVIEW PAPER ON SHELL AND TUBE TYPE HEAT EXCHANGER

Abstract
This is a review paper based on design optimization of shell and tube type heat exchanger (STHE). It contains numbers of parameters which influence the increased heat transfer of STHE. For designing of STHE, TEMA standards are used to define the main configuration of exchangers and their classification for industry use. They are used along with the ASME code to design and fabricate exchangers, as well as customer specifications. We include the future works suggested to enhance the design to increase the effectiveness of STHE. Required results also included in our paper.The design optimization of STHE is done to achieve the desired heat transfer rate while considering various aspects. This optimization process typically involves minimizing factors like initial cost, operating cost, pressure drop, heat transfer area, weight, or material usage. Keywords - STHE, effectiveness, baffles, tube layouts, type of flow
