Investigation of Heat Transfer from Convective and Radiative Stretching/Shrinking Rectangular Fins

We study the efficiency of shrinking/stretching radiative fins to improve heat transfer rate. To evaluate competence suggested fins, influence shrinking/stretching, thermogeometric parameters, surface temperature, convection conduction, radiation and Peclet number is investigated. The problem solved numerically using a shooting method. validate numerical solution, results are compared with solution differential transform Temperature distribution increases rise in conduction parameters when number, stretching/shrinking, ambience, temperatures raised. temperature fin’s tip as ambient increase, decreases for enhanced parameters. Radiation cause fin increase shrinking decrease stretching, which shows an important role analysis mechanical engineering. formulated model also studied analytically, result qualitatively good agreement.
