چکیده انگلیسی


• Measurement of thermal conductivity and viscosity of Fe3O4/EG nanofluid.
• Experiments are undertaken for diff. concentration, temperature, sonication time.
• Parameters are optimized for minimum viscosity and maximum thermal conductivity.
• RSM is employed to evaluate linear, quadratic and interactive effects.
• Statistical models are developed for viscosity and thermal conductivity.

Present study deals with experimental measurement of thermal conductivity and viscosity of Fe3O4 ethylene glycol nanofluid and multi-response optimization of conditions for maximum thermal conductivity and minimum viscosity of nanofluid. The thermal conductivity and viscosity were measured at 0.2, 0.5 and 0.8 vol% of concentration, 20, 50 and 80 °C temperature and 1, 2.5 and 4 h of ultrasonication time. Response surface methodology was employed to evaluate linear, quadratic and interactive effects of response variables. The multi response optimization yields the conditions: concentration 0.8 vol%, temperature 80 °C and ultrasonication time of 3.6 h. The optimum values of thermal conductivity and viscosity were 0.702 W/m K and 3.14 mPa s respectively and experimental values of thermal conductivity and viscosity were 0.694 W/m K and 3.10 mPa s with composite desirability (D) equal to 0.993.
