Heat-Transfer Tests of Aqueous Ethylene Glycol Solutions in an Electrically Heated Tube

Abstract

Tests were conducted to determine heat transfer characteristics of AN-E-2 ethylene glycol and other ethylene glycol-water mixtures as part of an investigation of the cooling characteristics of liquid-cooled engines. Liquid temperatures ranged between 100-250 deg F, liquid flow rate between 0.17-2.50 lb per sec, Reynolds Number between 5000 and 300,000, and heat flux between 4-36 BTU per sec per sq in. In three comparative tests, using varying amounts of glycol-water, it was found that heat transfer coefficients of these combinations were 3.8, 2.8, and 1.4 times higher than those of AN-E-2 ethylene glycol.
