- The rheological behaviour of ethylene glycol-based nanofluids containing hexagonal scalenohedral-shaped α -Fe 2 O 3 (hematite) nanoparticles at 303.15 K and particle weight concentrations up to 25% has been carried out using a cone-plate Physica MCR rheometer. The tests performed show that the studied nanofluids present non-Newtonian shear-thinning behaviour. In addition, the viscosity at a given shear rate is time dependent, i.e. the fluid is thixotropic. Finally, using strain sweep and frequency sweep tests, the storage modulus G ', loss modulus G ″ and damping factor were determined as a function of the frequency showing viscoelastic behaviour for all samples.
