Through this research article, we report our primary work of Zinc Oxide-Water (ZnO-H2O) based nanofluid indicating increase in heat transfer as a function of concentration of ZnO nanoparticles. The main objective of present is to analyze effect of nanoparticles concentration on thermal conductivity of nanofluid. The enhancement in heat transfer of nanofluid was observed with concentration, but in irregular manner. The irregularity in enhancement of thermal conductivity is discussed using orthokinetic aggregation effect. The thermal conductivity ratio of ZnO-H2O based nanofluid suggest that as-prepared nanofluids exhibits good heat transfer characteristics and found suitable for heat exchanger application.
