Original Abstract

The aim of the submitted work is in the comparison of the two methods used for a detection of the thermal volume expansion coefficient (β) of heat transfer fluids. Thermal volume expansion coefficient is one of the fundamental thermo-physical parameters monitored in the heat transfer fluids for solar collectors. First methods is based on commonly used Archimedes law principle and second deals with the determination via Abbe refractometer. Measurement of β using a Abbe refractometer is not very common, but in a practical way simpler and faster than the methods based on the Archimedes principle. The identified thermal volume expansion coefficient under two different methods was compared and also has been found the relation between refractive index and β of the heat-transfer fluids measured by Abbe refractometer.
