Measurements of the distribution of the flux of energy in the focus of a solar concentrator with visualization techniques

  • Published:
Il Nuovo Cimento C

Summary

This work analyses the setting-up of an optical head which allows the visualization of a section of the distribution of the flux of energy along the focal axis of optical systems in general and of solar concentrators in particular. A circular-type solar concentrator, with the reflector consisting of a plastic lamina aspirated by means of a pump, has been built. The distribution of the energy flux in the focus of this concentrator has been calculated by the theoretical method. Results are compared with experimental data obtained by means of the optical head.

Riassunto

Questo lavoro analizza la messa a punto di una testa ottica che consente la visualizazione di una sezione della distribuzione del flusso di energia lungo l'asse focale di sistemi ottici in generale e in particolare di concentratori solari. È stato realizzato un concentratore solare di tipo circolare, con riflettore costituito da una lamina di plastica aspirata mediante una pompa. La distribuzione del flusso energetico nel fuoco di questo concentratore è stata ricavata per via teorica. È stato fatto un confronto con misure sperimentali ottenute mediante la testa ottica.
