DEVELOPMENT AND EVALUATION OF A LABORATORY BENCH SCALE HEAT TRANSFER APPARATUS

Abstract

This report describes work done on the development and evaluation of a laboratory bench scale heat transfer apparatus for determining the heat transfer efficiency of automotive coolants. A bench unit was constructed and used for measuring forced convection heat transfer coefficients of several typical coolants. Measurements were made under boiling and non-boiling conditions. The method employed uses a small electrically heated wire as a heat dissipating surface and at the same time as a resistance thermometer for determining surface temperature. The usefulness of the unit has been demonstrated by preliminary data showing significant differences in heat transfer ability of presently used coolants, especially at higher metal temperatures. The unit is also capable of providing data on the effect of corrosion or other surface reaction on heat transfer.
