ABSTRACT:- The thermal performance of solar still with an indirect evaporator-condenser has been studied for the Garoua (9°23' N; 13°23'E ; altitude 241 m) climatic conditions. The brine is heated in a flat plate heater coupled with an evaporator-condenser. Equations describing heat and mass exchanges in evaporator-condenser are recalled and numerically solved. The effects of climatic and other system parameters have also been studied. The studies have been made in terms of overall thermal efficiency as well as hourly yield. Our theoritical analyses reasonably agree with experimental results published in the literature for the practical heat fluxes encounted in solar stills.
