Comparison of Ethylene-Glycol Coolants With/Without Additives for Subcooled Boiling Conditions

This paper presents experimental data comparing the thermal performance of aqueous ethylene-glycol mixtures with and without additives. These additives are used to provide corrosion protection, but their presence can also improve the coolant thermal performance. The experimental results show that the coolant with additives yields wall temperatures approximately 50°C lower than the non-additive coolant at the maximum heat flux condition.
