Recent developments in Nano technology applications in direct absorbing solar collectors: A Review

Jiten Makadia, Nirav Meghpara, Sanket Pandya, Pooja Ghodasara


Solar energy harnessing is widely promoted amongst the nations so as to encourage environment conservation. Use of solar energy is very important in the context of global warming and decrease in carbon dioxide generations. Here it becomes important for the researchers to find new methods for optimum utilization of solar energy in collectors by design modifications thereby reducing heat losses along with considering the reductions in high initial costs. Addition of nano fluids in base fluids will significantly enhance the thermo physical properties of base fluid as far as heat transfer rates are concerned. This method proves very much efficient in solar collector applications by direct absorption. Advantages are reduction in overall size and thereby reducing manufacturing costs and improvement in efficiencies. This paper presents the review of work done in this field in past half decade. Along with, significant research gaps are deliberately studied so as to promote the research work in this field.
