Experimental Study of the Influence of Nanoparticles on Evaporation of Fluids

Evaporation of nanofluids based on distilled water and silicon-dioxide, zirconium-dioxide, aluminum oxide, and diamond nanoparticles has been experimentally studied. The mean nanoparticle sizes are 25 nm for SiO2, 105 nm for ZrO2, 43 nm for Al2O3, and 5 nm for diamond. Evaporation processes have been investigated using an STA 449 C Jupiter (NETZSCH) simultaneous thermal analyzer. The dependence of the evaporation rate on the nanoparticle volume concentration has been studied. It is shown that the fluid evaporation rate monotonically increases with an increase in the nanoparticle concentration.
