Thermal-Conductivity Measurements of Aviation Kerosene RP-3 from (285 to 513) K at Sub- and Supercritical Pressures

The thermal conductivity of a representative endothermic hydrocarbon aviation kerosene fuel RP-3 was accurately measured using the classical transient hot-wire method at sub- and supercritical pressures. The measured data cover a temperature range of 285 K to 513 K and a pressure range of 0.1 MPa to 5 MPa. The expanded uncertainty of the experiment was less than 3.0 % based on an uncertainty analysis. Furthermore, the measured data were correlated using a polynomial equation to analyze the deviations; 97.6 % of the measured data were within a 2 % error band. The average absolute deviation (AAD) and maximum absolute deviation (MAD) of the fitted thermal-conductivity data were 0.209 % and 2.31 % for all values, respectively.
