A comparative experimental investigation of dynamic viscosity of ZrO/DW and SiC/DW nanofluids: Characterization, rheological behavior, and development of new correlation.

In general, A nanofluid is a substance in which solids and fluids are mixed. The nano-powder of zirconium oxide (ZrO) and silicon carbide (SiC) was dispersed into the distilled water (DW) using the widely adopted two-step technique. A Brookfield viscometer was used to measure the viscosity of the nanoparticles of ZrO/DW and SiC/DW, where the temperature ranged between 20 and 60 °C and different solid volume fractions of 0.
