Abstract
Test results have been obtained on the thermal performance of aqueous mixtures of propylene-glycol and ethylene-glycol for conditions simulating automotive engine operation. For the present study, thermal performance is defined as the test section surface temperature for a given set of operating conditions. In addition to testing over a wide range of surface heat fluxes up to 2.3 MW/m2, data were also obtained at different mixture concentrations. For all cases considered, both coolant mixtures provided similar results.
