Heat transfer performance of nanofluids in heat exchanger: a review

Energy is a key aspect of any country’s economic development. Improving heat transfer performance leads to saving energy. Nanotechnology has role play in optimizing exchangers. Fluids containing nanosized particles are called nanofluids. Nanofluids have higher thermal conductivity than typical liquids. This paper outlines current research on convective performance, thermophysical properties, particle size, and volume concentration effects nanofluid studies.
