Experimental comparison of heat transfer from a rectangular fin array and a circular tube bundle under free and forced convection

Key Points

• Heat transfer rates from rectangular fin arrays and circular tubes show significant variations under different convection conditions.
• In forced convection, the performance of fin arrays improves, leading to efficient thermal management in engineering applications.
• The study utilized both experimental and theoretical approaches to analyze heat transfer mechanisms across differing geometries.
• Findings suggest optimizing designs for heat exchangers may enhance performance in various industrial applications.
