Thermal Conductivity of Gaseous Methane, Propane and a Binary Mixture of [xCH4 + (1-x)C3H8] with x = 0.95 at T = (253 to 373) K and p up to 14 MPa
The transient hot wire technique is an absolute method for measuring the thermal conductivity of fluids. In this work a transient hot-wire device was used to measure the thermal conductivity of gaseous methane, propane and a mixture xCH4 + (1-x)C3H8, where x ? 0.95. The sensor consists of two 10 ?m-diameter platinum wires with lengths 15 and 4 cm. The wires are placed in series on different branches of a Wheatstone bridge and all the necessary corrections were applied to ideal model for the measurement of the thermal conductivity,. The correct operation of the device was confirmed by preliminary measurements of methane, propane and nitrogen at the temperature range (253 to 373) K and pressure range (0.1 – 14) MPa Our thermal conductivity results were compared with the literature data and the transport property models implemented in NIST REFPROP .
