摘要

摘要: 利用广义对应态法则对吸热型碳氢燃料RP-3的5种替代模型的密度、黏度、导热系数和比定压热容进行了数值计算.计算温度变化范围为300~800K,压力变化范围为3~6MPa.结果表明:不同替代模型均能定性重现RP-3在拟临界温度附近的物性急剧变化;由53%正十一烷,18%正丁基环己烷,29%1,3,5-三甲基苯组成的3组分替代模型在预测RP-3物性上表现最优,相对于实验数据,300~700K内密度相对误差均小于0.08;替代模型的相对分子质量越大,预测的拟临界温度越高,对拟临界温度下物性值的影响无显著规律.

Abstract: 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.
