چکیده انگلیسی


• Y3Al5O12–EG nanofluids exhibit Newtonian behavior.
• Viscosity decreases with temperature.
• Thermal conductivity increase nonlinearly with volume concentration of particles.

The paper presents results of measurements of basic thermophysical properties of ethylene glycol based yttrium aluminum garnet (Y3Al5O12–EG) nanofluids. Nanofluids used in presented experiments were prepared with two-step method based on commercial nanoparticles. Basic rheological properties were investigated on HAAKE MARS 2 rheometer (Thermo Electron Corporation, Karlsruhe, Germany). Dynamic viscosity curves in the range of shear rates from 10 to 1000 s−1 at a constant temperature of 298.15 K were determined. Additionally, the temperature dependence of the viscosity in the range from 273.15 K to 333.15 K was measured. To determinate thermal conductivity of nanofluids a KD2 Pro Thermal Properties Analyzer (Decagon Devices Inc., Pullman, Washington, USA) was used. The dependence of thermal conductivity of Y3Al5O12–EG nanofluids on the concentration of nanoparticles was measured at constant temperature of 298.15 K.
