Abstract
The aim of this research was to increase the engine car efficiency by adding an innovative material called hybrid MWCNT/Al2O3 nanofluids. A volume ratio instance for investigations is 0.05 MWCNT mixed with 0.05 Al2O3 in distilled water (DW). The experimental temperature setup was in the range from 50 °C to 70 °C. The results demonstrate that as temperatures increase, specific heat and thermal conductivity increase significantly, while viscosity and density gradually decrease. At 70 °C, the highest thermal conductivity of 1.143 W/m.K was achieved in the presence of hybrid MWCNT/Al2O3 nanofluids. Furthermore, it was found that the correlation coefficient for thermal conductivity is 97.06% R2.
