Abstract
Experimental data on the thermal conductivity coefficient and viscosity coefficient of nanodiamond nanofluids are presented. Distilled water and ethylene glycol were used as the base fluid. Dependences of transport coefficients on concentration are obtained. It was shown that the thermal conductivity coefficient increases with increasing nanodiamonds concentration. It was shown that base fluids properties and nanodiamonds concentration affect on the rheology of nanofluids.
Highlights
Nanoparticle colloidal suspensions, referred to as ‘nanofluids’ [1], have potential application in many heat transfer areas because of their intriguing properties such as a considerable increase in thermal conductivity, long-term stability and prevention of clogging in micro-channels [2,3]
It was obtained that the coefficient of thermal conductivity of nanofluids increases with increasing nanodiamond concentration in all considered cases
It is shown that the increase in the thermal conductivity coefficient is greater for fluids with lower thermal conductivity
