Abstract

Heat Exchanger is a device used to transfer heat between two or more liquids at different temperatures. The purpose of this study is (a) to design efficient shells and tubes using technology to increase heat transfer coefficients at the side of the shell and tube simultaneously, (b) To determine the optimized variables to produce a maximum heat transfer coefficient and a minimal pressure drop, (c) to analyze the effect of applying helical baffle and coiled wire insert technology on overall heat transfer coefficient and pressure drop. On the shell side, segmental technology is modified into helical baffle technology by regulating the tube pitch and distance between baffles. The optimization method used is Genetic algorithm (GA). The variable used for optimization on the shell side is the helical baffle angle (β) and the distance between the helical baffle (Lbc). Variables used for tube side optimization using coiled wire insert …
