Studies of energy contribution input by electromagnetic wave radiation by a circular black body, heated using a Solar paraboloid concentrator.

solar energy

This work is based on the field of energy physics and particularly affects solar energy which is new and renewable to heat a circular black body placed at the focus of a dish concentrator. The principle chosen to study the energy input of the heated body is limited to the analysis of the radiation, without taking into account the thermal conduction in the air and the thermal convection in the materials. To ensure the reliability of numerical calculations and graphical representations, the MATLAB software was chosen for all operations and programming. In these cases, the results obtained are analyzed and interpreted according to the magnitudes of the constituent elements of the system (paraboloid, blackbody) and discussed according to the effect of the presence of the atmosphere on the solar constant or in its absence. This study allows researchers to determine the color of a heated body at a given temperature by studying Planck's function. For the two black body shapes studied, the wavelength calculations correspond to the maximum values of the luminances making it possible to prove that this color belongs to the Infrared (IR). For this study, we set the dimensions of the solar concentrator (height, focus), the black body and that of gray, taking into account that the latter is smaller in order to neglect radiation losses. We find that the black body heated in our study emits Infrared.
