In this study, fast filling process of NGV cylinders is simulated in a FORTRAN based computer
program. In this model, AGA-8 equation of state was utilized to compute compressibility factor
and other required thermodynamic properties such as internal energy, enthalpy and specific heats
of natural gas. The accuracy of model was evaluated by comparing the acquired results with real
data. The real data was gathered for three kinds of NGV tanks at a CNG station. Our comparison
demonstrated that, there is a reasonable agreement between modeling and experimental data at the
whole charging period. Furthermore, it is demonstrated that temperature elevation of natural gas
during the fast filling process is the main factor that prevents the 100% full fill in each refueling.
