Nanofluids for solar collector applications: A Review

摘要

Nanofluids are embryonic fluids that exhibit thermal properties superior than that of the conventional fluid. Theapplication of nanofluids is to achieve the highest possible thermal properties at the smallest possible concentrations,by homogeneous dispersion and stable suspension of nanoparticles in the host fluids. Nanofluids plays vital role invarious thermal applications such as automotive industries, heat exchangers, solar power generation etc. Mostly heattransfer augmentation in solar collectors is one of the key issues in energy saving, compact designs and differentoperational temperatures. In this paper, a comprehensive literature on thermophysical properties of nanofluids and theapplication of solar collector with nanofluids have been compiled and reviewed. Recent literatures indicate theconventional heat transfer using nanofluids and their specific applications in the solar collector.
