Shell-and-tube heat exchangers are among the most widely used thermal equipment in power plants, chemicalindustries, and HVAC applications due to their robust construction and high heat transfer capacity. Improving theirperformance while maintaining structural stability is a key engineering challenge, especially in applications requiringcompact design and enhanced efficiency. This study focuses on the design and experimental analysis of a shell-andtube heat exchanger equipped with enhanced fins for improved heat transfer. Various fin geometries—rectangular,helical, and perforated fins—were incorporated into the tube bundle to analyze their effect on thermal performance.Experimental testing was conducted using hot water as the tube-side fluid and cold water on the shell side. Parameterssuch as overall heat transfer coefficient, effectiveness, log mean temperature difference (LMTD), and pressure dropwere evaluated for each fin configuration. Results indicated that perforated fins significantly improved turbulenceand enhanced heat transfer by up to 22%, while helical fins provided a good balance between heat transferenhancement and moderate pressure drop. The study concludes that fin geometry plays a crucial role in optimizingheat exchanger performance, and enhanced fins offer a promising pathway for designing more compact and efficientthermal systems.
