Nanofluids are engineered colloids, which find a wide range of applications because of their enhancedheat transfer capacity. The nanoparticles, homogeneously dispersed in the base fluid (water in our case) inctrease the effective thermophysical properties. Nanofluids find a wide range of allicatiosns in biomedicines, industries, nuclear reactor cooling, and heat exchangers. In this paper, ceramic nanofluids are used for the enhancement of the heat carrying capacity of base fluid. The thermal behaviour of the nanofluids is derived using the available Nusselt number from the literature.Heat transfer is calculated using practical Nusselt number range. The present work aid in the flow characterization of nanofluids for different geometric specification of flat plate solar collector and solar ducts.
