CFD Analysis of Heat Transfer Characteristics in Heat Exchanger having fins with different Geometries-A Review

A heat exchanger is a device that transfers thermal energy between two or more fluids in thermal contact that are at different temperatures. They're employed in a variety of industries, including aerospace, chemical manufacturing, power plants, refineries, and HVAC refrigeration. In industry, the optimal design and efficient functioning of the heat exchanger and heat transfer network are critical for increasing efficiencies and lowering production costs and energy consumption. Heat transmission has long been a major factor in the design of electrical components, chemical reaction containers, apparatus, heat exchangers, and insulating materials, among other things. In some applications, it is critical to limit heat loss, while in others, it is critical to swiftly release excess heat into the surrounding atmosphere to avoid overheating. Finned surfaces give more support and so operate as efficient heat sinks by facilitating faster heat transmission. To better understand the elements affecting heat transfer over the length of the fin, we will use ANSYS Workbench® to simulate heat transfer processes via multiple finned surfaces of varying shapes and materials. The fins were created in the ANSYS Workbench environment while maintaining a consistent total exposed surface area. With different operating conditions and settings, the models were rendered and simulations were run. This study compiles and tabulates the results. Pin Fin, Plate Fin, and Elliptical Pin Fin geometries will be employed in this experiment.
