Experimental study on rheology with carbon nanotubes/water nanofluids

In this thesis, we worked with various concentrations of carbon nanotubes/water nanofluids at wide temperatures range such as 0-50°C and viscosity of CNT nanofluids have been investigated. Additionally, time effect and mixing effect have been researched with experimental methods. CNT/water nanofluids have been shown different behavior than compared to conventional fluids. They were showing time dependent effect during the experimental periods. Hence, it shows to different behavior between low shear rates and high shear rates and the mixing effect is active on change of viscosity. During the experiment it has shown that viscosity was changing with waiting time and each waiting time was making more viscous than previous measurements. Besides, the temperature effect has been investigated at low and high concentrations. It would appear that viscosity increase with decrease temperatures and increase particle concentrations.
