Production of ethylene glycol based nanofluids, experi̇mental analysis of viscosity and thermal properti̇es

In our work, analysis and measurements of the produced particles were performed after the production of CuO and ZnO nanoparticles. Nanoparticles produced by using pure water, ethanol and ethylene glycol materials with nanoparticles were passed through the experimental setup and the thermal conductivity coefficient (k) and heat transfer coefficients (h) were determined. In experimental measurements with a Reynolds number of around 1600 are provided an average improvement of 16.5% in ZnO and 13.3% in CuO in heat transfer according to pure water. The graph was drawn after the viscosities of the fluids were changed according to the temperature. Reynolds numbers range have been changed from 846 to 2292 in the made experiments. In addition, the graphs showing the relationship between the heat transfer coefficients and the Reynolds number were drawn.
