In the digital age, fins are often used as effective elements for heat transfer enhancement, extending the life and efficiency of devices while achieving superior thermal management and high performance. Understanding forced convection through fins provides valuable insights for optimizing heat management in many industries such as aviation, heat exchangers, electronic equipment, IC engines, and underground mine ventilation system applications. The current research focuses on the flow and heat transfer characteristics of Pin-Fin using CFD and theoretical approach. A pin fin model for forced convection has been designed and held horizontally inside the rectangular duct in this investigation. The pin fin is made of Brass and measures 1.2 cm in diameter and 12 cm in length. The Fin is enclosed by a 15cm x 10cm x 100cm rectangular duct. The objective of this research work is to make a comparison of the heat transfer coefficient, fin efficiency, and efficacy at various Reynolds numbers to analytical values. ANSYS Geometry is used to create the three-dimensional model, which is then meshed by ANSYS Mesh. The CFX solver is used to obtain CFD results. The outcome of the CFD simulation is in good agreement with analytical approach.
