An Inexpensive Technique to Determine the Parameter in Free Convection Heat Transfer from Two Parallel Heated Vertical Plates

ABSTRACT

Heat transfer using natural convection and fluid flow is an important phenomenon in daily life and engineering applications such as HVAC systems of building, harvesting energy using non-conventional energy sources, extraction of heat from electronic equipment and cooling technologies integrated in computer systems. The present study investigates about the two experiments: (1) Heat transfer taking place between two parallel-Vertical Plates by natural convection, in which two walls are adiabatic and other two ends are open to the ambient air and (2) The estimation of constant C in the expression of Nusselt Number from the data of temperature distribution obtained by performing experiments using a parallel Vertical-Plate by maintaining steady state conditions. Two parallel vertical plates made of Aluminium are allowed to cool in air, to ensure that Lumped capacitance formulation is valid. In the first case the Nusselt and Rayleigh numbers were calculated experimentally and compared with the value available from the correlation which is found to be in good agreement. In the second case, the value of C in the expression of Nusselt Number was calculated using Least Square Residual Method and validated this result by introducing this value into the correlation available. The experimental setup which is required has been designed and fabricated.
