摘要:The development and performance of shell and tube heat exchanger is an issue of great challenge and part of emerging nascent technology. The performance optimization would serve a great contribution to placate the inflated operating costs as well as energy crisis. This paper showcases all the empirical results obtained from the real time system analysis in various working conditions. Further it represents comparison for several shell-and-tube heat exchangers with baffle angle parametric variation. Like Various angles 150 , 250 ,350 , 450 . system identification has been carried out by two methods viz, CFD analysis and theoretical calculation. The combined results with respect to same shell-side flow rate show that, the heat transfer coefficient of the heat exchanger with helical baffles is higherthan that of the heat exchanger with segmental baffles while the shell-side pressure drop of the former is even much lower than that of the latter. Further enhancement techniques should be incorporated in order to enhance shell-side heat transfer based on the same flow rate. The comparativeanalysis of heat transfer coefficient per unit pressure drop shows that the Segmental Baffle Heat exchanger have significant performance advantage over Helical Baffle Heat exchanger for the same geometrical configurations. The performance enhancement of heat exchanger with helix baffle angle optimization could be considered as an innovation.
