摘要：

Experiment on mass diffusion of fluorescent Rhodamine B in Cu-water nanofluids is carried out to investigate enhancement effect of mass transfer in binary nanofluid. An optical experimental system is designed to measure the diffusion coefficient of Rhodamine B in the nanofluid with different nanoparticle volume fractions under different temperatures. The effects of nanoparticles and fluid temperature on mass diffusion inside the nanofluid are discussed from the experimental data. The experimental results show that the diffusion coefficient of fluorescent Rhodamine B in nanofluids is bigger than that in de-ionized water.
