Experimental investigation on viscosity of Cu-H2O nanofluids

摘要: A procedure for preparing a nanofluid that solid-liquid composite material consists of solid nanoparticles with sizes typically 1–100 nm suspended in liquid was proposed. By means the procedure, Cu-H2O nanofluids and without dispersant were prepared, whose sediment photographs particle size distribution given to illustrate stability evenness suspension dispersant. The viscosity measured using capillary viscometers. mass fractions(w) copper experiment varied between 0.04% 0.16% temperature range 30–70 °C. experimental results show SDBS concentration are major factors affecting nano-copper suspensions, while effect fraction Cu on is not as obvious chosen experiment. apparent nano-suspensions decreases increase, increases slightly increase dispersant, almost keeps invariability increasing Cu. influence nano-suspension relatively large comparing nanoparticle concentration.
