Experimental Set-Up for The Measurementof The Thermal Conductivity of Liquids
Abstract. 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.
Keywords: measurement and instrumentation, thermal conductivity of
liquids, transient hot wire method.
