Numerical computations of density

viscosity

thermal conductivity and specific heat of five kinds of surrogate models for endothermic hydrocarbon fuel RP-3 by extended corresponding state law were conducted. In the computation

the temperature and pressure ranged from 300K to 800K and from 3MPa to 6MPa

respectively. Results indicated that all surrogate models could qualitatively reproduce sharp variation of physical property of RP-3 in the vicinity of pseudo-critical temperature; a three-species surrogate model consisting of mole of 53% n-undecane

18% n-butylcyclohexane

29% 1

3

5-trimethyl-benzene performed best among five physical surrogate models in predicting physical property of RP-3. The relative errors of this surrogate model for density were less than 0.08 at the temperature from 300K to 700K. Pseudo-critical temperature increased with growing relative molecular mass of surrogate models

showing that there was no obvious relationship between thermal properties under pseudo-critical temperature and relative molecular mass of surrogate models.
