Experimental set-up for the measurement of the thermal conductivity of liquids
The paper describes an in house made experimental set-up that measures the thermal conductivity of liquids. The measurement principle is based on the Transient Hot Wire Method. The theoretical bases of the measurement method are firstly presented, and then our original experimental implementation is described. The hardware as well as the software design reveals the simple configuration of the measurement set-up that contains high performance inexpensive components. It is also simple to use and well suited for research laboratories, data being stored either in text, or in graphical files. Finally, based on experimental results, the measurement accuracy and sensibility performances are discussed and compared with other instruments in literature.
