Abstract

This thesisfocuses on renewableenergies, and aims to quantifyheat exchangeusinganumericalstudyandsteady-statemathematicalmodelingofadouble-passsolar collector. Energy balance equations have been established for the variouscollector components (glass, absorber, heattransferfluid and bottom plate). Thesystems of equationsweresolvedusing the finite-differencemethod to calculatethe temperatures of each collector element. In addition, a detailedparametricstudyofthesolaraircollectorswascarriedout,andthenumericalsimulationwasverifiedusingaMatlabprogram.Theresultsshowedanincreaseinairtempérature.
