Abstract Thermo-physical properties for surrogate aviation kerosene RP-3 were developed in this study to lay a foundation of the further investigation of the heat transfer calculation and experiment. The specific heat calculated from different surrogate models of the RP-3 was compared with the experimental data. The effects of three kinds of species, i.e. paraffin, cycloalkanes, benzenes, on thermo-physical properties were analyzed. There are the big differences of thermal properties at pseudo-critical temperatures. Based on the previous research of surrogate models and the GC-MS analysis of RP-3, a four-species surrogate was proposed. The numerical results for thermo-physical properties were in good agreement with the experimental data, including the specific heat, density and viscosity.
