Year: 2026
Type: article
Abstract: The study investigates heat transfer in air under forced convection, facilitated by a heat flow at normal atmospheric pressure. It presents a computational model using an iterative method to simulate mass and energy exchanges with heat transfer equations. Numerical simulations examine air flow and heat transmission in а flow path heat under atmospheric conditions. The prediction setup consists оf Circular, smooth test sections characterized by а hydraulic diameter оf ( ) meters, length of ( ) meters, transverse pitch of ( ) meters, fin height of ( ) meters, fin thickness of ( ) meters, and a fin spacing of ( ) meters. The system includes both inlet and outlet flows, with air introduced at ( ) degrees Celsius. Results show overall heat transfer coefficients ranging from ( ) to ( ) W/m²·K across Reynolds numbers from ( ) to ( ), with heat inputs between ( - ) watts. This study offers оf аn important insights tо the flow heat transfer behavior оf air оn horizontal tube within a path heat under standard atmospheric conditions as well the tube and fins are constructed from copper. The flow region size was determined by observing the expansion of flow zones and was assessed for all heat tests using an iterative method projected by Excel application. Finally, over ( ) correlations for these phenomena were made
