Heat Transfer Analysis of Solar Concentrator Developed For Cooking Purpose

Abstract

Solar cooking is said to be one of the most efficient ways of using solar energy. People in both developed and developing countries have been urged to seek out and use clean and sustainable energy options as demand has grown. Solar technology has enormous promise for meeting the world's energy demands. Its present contribution to the globe, however, is small. The key reason is the system's high initial cost of construction. The heat analysis of a parabolic solar concentrator was investigated in an experimental investigation. An experimental apparatus is a parabolic concentrator with major (a) and minor (b) axes of 55 inches and 53 inches, respectively. The experiments are conducted at the MITS campus, Gwalior, India, in the solar energy lab. The average ambient temperature is 40°C on the day experiment was performed. The result shows that the maximum temperature inside the pot reached was recorded as 84.6°C. The overall heat loss is expected to be 93.77 MJ and thermal efficiency is 0.162%.
