Design And Fabrication Of A Heat Exchanger For increasings Efficiency

Abstract

This study presents the design and fabrication of a shell and tube heat exchanger aimed at improving thermal efficiency. Experimental and computational analyses were conducted under various loading conditions. The performance was evaluated to identify optimal operational settings. The findings confirm efficient heat transfer with cold fluid in the shell and hot fluid in the tubes.The objective of this study is to design and fabricate a shell and tube heat exchanger and analyze its performance under varying conditions. The goal to increase the efficiency of heat exchanger .This study focuses on the design and fabrication of a heat exchanger to improve thermal efficiency. The LMTD (Log Mean Temperature Difference) method is used for thermal analysis and design optimization and material selection are carried out based on performance and cost factors.The fabricated unit is tested, and results are analyzed to validate efficiency improvements. Tube length 4 meters, number of tubes 6 Parallel flow efficiency 41.71% Counter flow efficiency 46.89% Tube length 5 meters, number of tubes 7 Parallel flow efficiency 60.80% Counter flow efficiency 68.24% Efficiency increases with tube length due to increased heat transfer area Counter flow configuration always shows higher efficiency than parallel flow
