A REVIEW OF THERMAL ENERGY STORAGE MATERIALS USED IN VARIOUS TYPES OF SOLAR COOKERS

MECHANICAL ENGINEERING

With the reckless use of non-renewable sources of energy, the need of the hour is to look for alternatives and solar is one of the best and abundantly available alternative . The utilization of solar energy is one of the possible alternative solutions for the cooking the food, but its reliability is less due to intermittent nature of solar energy. The intensity of solar energy varies throughout the day and also varies with the months. The reliability of solar energy may be improved to some limit by designing the heat storage system for solar based cooking system. This paper is a review on various techniques used to make the different types of solar cookers work effectively during the night time . The references are taken from various research papers already published in this domain but on different types of solar cooking arrangements. This paper tells how efficiently the concept of sensible and latent heat storage units can be used to facilitate the cooking in the later hours of the day .
