Abstract—In current study, an attempt has been made to develop a numerical method and a computer program to calculate the thermal properties of natural gas mixture such as enthalpy and internal energy in addition of the compressibility factor using AGA8 state equation. The method has been applied to a typical Iranian natural gas mixture to calculate the thermal properties of the gas. Finally, the developed program has been utilized to model single reservoir fast filling process of a typical natural gas vehicle on-board cylinder. The computed results have been compared with simulation results of same process (fast filling) in which the pure methane was acted as working fluid. The results show the similar trends and good agreements.
