Abstract

Thermal conductivity of rocket propellant (RP-1 fuel) has been measured with a coaxial-cylinder (steady-state) technique. Measurements were made in the temperature range from (292 to 732) K and at pressures up to 60 MPa. The total uncertainty of thermal conductivity, pressure, and temperature measurements were estimated to be less than 2 %, 0.05 %, and 30 mK, respectively. The onset of the effects of thermal decomposition (chemical reaction) on the thermal conductivity of RP-1 at temperatures approximately 650 K was found. The measured values of thermal conductivity were compared with the data reported in the literature and with the values calculated from a reference correlation equation. Average absolute deviation (AAD) between the present data and the values reported in the literature was 1.0 %. An empirical model was developed to predict the thermal conductivity of RP-1 (within 2.0 %) with just the thermal conductivity value at reference temperature ^T₀ = 293 K, ^λ₀ as an input.
