Pinch Analysis of a Heat Exchanger Using Numerical and Analytical Simulation

The thermal energy transfer characteristics of heat exchangers with thermal fins and evaluates their economic feasibility.It uses computational fluid dynamics simulations and economic analyses to examine various fin geometries, materials, and configurations.The results reveal that fin design parameters, such as height, thickness, spacing, and material properties, significantly influence heat transfer efficiency.The study emphasizes the importance of optimizing these parameters to balance thermal performance and costeffectiveness.The findings guide engineers and policymakers in selecting and optimizing thermal fins.A range of water flow speeds of 0.1, 0.5, and 1 m/s was used, and the dimensions of the fins were reduced in a manner commensurate with the nature of thermal energy transfer and to reduce the manufacturing cost.The study shows that thermal energy transfer through fins increases with fluid flow speed, with the pipe's exit temperature reaching 88 degrees Celsius at 0.1 m/s and 96 degrees Celsius at 0.5 m/s.The fins' temperature distribution varies, reaching 88 degrees Celsius, 94 degrees Celsius due to fin length changes, and 91 degrees Celsius despite fin size changes.The study also analyzed energy transfer through different shapes and flow speeds, finding that shape 1 transferred 340 W at 1 m/s, shape 2 decreased to 144 W, and shape 3 increased surface area but not volume.
