Sažetak
An experimental research was conducted to investigate effects of nanofluids on heat transfer characteristics in a double-tube counter-flow heat exchanger. With nanoparticle mass fraction of 0.5%-2% and Reynolds number of 4500-14500, friction factor was analyzed by using four nanofluids, i.e., CuO- water, Al2O3-water, ZnO-water, and SiC-water nanofluids. Results show that SiC-water nanofluid with a mass concentration of 1.5% has the best improvement of heat transfer performance, and 1% CuO- water nanofluid has the lowest friction factor when Reynolds number varies from 4500 to 14500. Based on testing results of Nusselt number and friction factor, the 1% CuO-water nanofluid as a working medium inside a double-tube exchanger, shows a great advantage due to a relatively high heat transfer performance and a low friction factor.
