EFFICIENCY OF AN INVERSE METHOD TO DETERMINE NATURAL-CONVECTION HEAT

Abstract

The final aim of this study is to identify the value of convective heat transfer generated by a local perturbation analog to a sun patch. A first approach to this work consisted of developing a means of evaluating the local heat transfer based on the use of an inverse method. We first chose the well-known academic case of a vertical heated plane plate to generate natural heat convection transfer. Then, for several temperatures of the plate, a first validation of the chosen inverse method was obtained in the steady state. It consisted of a comparison between the results provided by the inverse method and those obtained by the use of thermocouples to measure the temperature inside the boundary layer. These two types of results are also compared with relations published in the literature. In conclusion, the authors observe that the inverse method is pertinent and gives satisfactory results.
