Lagoas solares de gradiente salino, estudo e análise

Abstract

This research presents the solar energy collection and storage device - so called salt gradient solar pond. The study consists on a short history of this technology, since its first observation as a natural phenomenon, until its largest and most recent applications. A review of systems installed in India and U.S.A., was performed to analyze which were the difficulties found and the system s performance. The study also displayed a thermal energy capture system components, a solar pond construction, its operation and analyses the necessary conditions for the salt gradient stability. An equations system that models the theoretical operation of a solar pond was proposed. At the end of the analysis, enough data was shown to bring clarity about the mains aspects of this kind of collector, its function and main potential applications.
