Abstract

In this paper, the thermal conductivity measurement experimental setup built on the principle of transient short filament method was tested using liquid toluene, and the results indicated that the measurements from the experimental setup are accurate and reliable. The thermal conductivity of liquid n-dodecane was experimentally measured within the temperature range of 317.97K to 610.54K and the pressure range of 1MPa to 20MPa. The effective data from the measurements, ignoring the influence of radiation, were fitted into a function related to temperature and pressure. The experimental values were compared with the fitted values, and the relative deviations between the experimental values and the fitted values were found to be mostly within ±2%, with the maximum relative deviation being 2.6%.
