Effect of RP-1 Compositional Variability on Thermophysical Properties



Marcia L. Huber, Eric W. Lemmon, Thomas J. Bruno


We compare experimental and predicted thermophysical properties of two samples of rocket propellant RP-1 obtained from different batches of RP-1 that exhibit compositional variations. One sample is atypical, due to a high olefin content. The effect of the compositional variation is shown for several thermophysical properties such as density, sound speed, viscosity, thermal conductivity and the distillation curve. We also compare two different surrogate mixture models that were developed for each fuel sample. The greatest effects are seen in the viscosity and the distillation curve.
