Radial Heat

A steady state thermal conductivity measuring setup based on the comparative radial heat flow method is presented. The setup consists of a pair of coaxial cylinders as its main components, with test fluid placed in the annular space between these cylinders with water tight cover plates at the top and bottom of the cylinders. Experiment involves heating the coil at the concentric-center of the inner cylinder; steady state data are acquired for the calculation of the thermal conductivity. Thermal conductivity is calculated by comparing the radial heat flow between the cylinders and the test fluid (comparative method). Thermal conductivity of water, glycerol, and ethylene glycol was measured for varying temperatures and is in good agreement with the published thermal conductivity values in literature.

A radial heat-flow apparatus has been constructed in Pyrex glass and used for liquid thermal conductivity investigations. The liquid under test fills the 1.25mm space between concentric cylinders and a measured quantity of heat flows inwards. After calibration using liquids of known thermal conductivity, new values are obtained for pyridine and three chlorofluoro­carbon oils. The apparatus can also be used for direct determinations when allowance is made for the temperature drop occurring in each of the glass walls. For this purpose, a determination of the thermal conductivity of the glass was made using a similar method. A discussion of the results is included.
