Optimisation d’un capteur solaire double passe à air et estimation des échanges de chaleur paroi-fluide.

2018

In this work, we present a study of the performance of a double pass flat solar collector for the production of hot air to supply and improve drying techniques. The cases of an absorber with and without fins are analyzed.Theoretical models for the double pass solar collector with and without fins have been established and solved numerically using codes developed in Fortran to obtain a global approach. Comsol Multi-physics code is used for a more local study. An experimental device has been designed to validate the results obtained numerically. One of the particularities of the solar collector developed in the laboratory is its insulation system. For this, a local bio-sourced material compos…
