Viscosity and Thermal Conductivity Characterization of Magnesium Oxide Nanofluids for Improved Automobile Thermal Management

Magnesium oxide (MgO) nanofluids are of great interest for enhancing the performance in thermal management especially in automotive applications, where efforts have been made to reduce parasitic losses from traditional cooling systems. These findings highlight the effects of Water–ethylene glycol and MgO nanofluids on viscosity and thermal conductivity in specific filling a gap in research that allows to clarify how these states behave at different temperature (T) and concentration (C) conditions. Test results demonstrate that the thermal conductivity of MgO nanofluids improved adequately /while its corresponding change in viscosity remained under control, affirming a significant improvement for energy savings by means heat transfer enhancement using new generation coolants based on this nano-additive. The results also provide useful information for design and development of automotive cooling systems, including real numbers on performance improvements that lead to more efficient and reliable thermal management designs.
