Abstract

In this work a design of solar cooker with mirror reflectors has been studied for two tracking modes and his performances are analyzed by the simulation of collected energy on the absorber of the cooker. The box of the cooker receives the solar radiation both directly and by reflection from the mirror reflectors. The plane mirrors with high optical reflectivity allows sun tracking in the north south direction (for seasonal tracking) as well as in the east west direction (for tracking during the day) by moving theses reflectors with the correct angles. Adding reflectors improves the performances of the cooker, which is interesting in particular in winter, where the elevation of the sun is relatively low. The combination of north-south and east-west facing mirror reflectors are favorable for more energy collection, the cooker is enabling to cook during the day and around the year.
