Abstract
The Design and Optimization of shell and tube heat exchanger requires great attention in order to develop a heat exchanger which can accomplish its desired task efficiently. This design of heat exchanger design was to minimize the overall cost as much as possible while making no compromises on the exchanger's heat duty. Hence the estimation of the minimum heat transfer area, required for a given heat duty was of utmost importance as it governed the overall cost of the heat exchanger. The Project was to solve the major problem faced by industry i.e. the overheating of Gas Engine Jenbacher JGS 320 GS-N.Linstalled at Masood Textile Mills. The Shell and Tube Heat Exchanger was used to cool the lubricating oil which was to optimize and to overcome the overheating problem. The Optimization techniques included, changing the flow direction, flow rates, varying the baffle cut and baffle spacing, using finned tubes and the combination of these methods were designed and evaluated and then best method with maximum mean thermal efficiency and required temperature changer was selected as a solution of problem.
