Progress and application of nanofluids in solar collectors: An overview of recent advances

Abstract

Sun is the vital source of energy on the earth and it is one of the most significant options in contrast to the traditional petroleum products. It is only because of its property to directly convert solar energy into thermal energy in form of heat energy and finally into electrical energy without any harmful environmental effects such as greenhouse gas emission and other environmental effects. The effective way to enhance the performance of solar energy system is to utilize a high-quality heat transfer fluid with superior thermophysical properties such as high thermal conductivity and hence nanofluid is the best option to enhance the performance of the system. The lack of petroleum products and its harmful effect on the environment inspired the researchers to think about the alternative source of energy and sun is the best alternative source of solar energy. The main aim of this review paper is to investigate the applications of nanofluid and its recent advancement in solar collectors.
