Thermodynamics Analysis of Cascade Reserviors Filling Process of Natural Gas Vehicle Cylinders

چکیده
The accurate modeling of the fast-fill dynamics occurring in Compressed Natural Gas (CNG) fueled vehicle storage cylinders is a complex process and to date those dynamics have not been thoroughly studied. Here, based on first law of thermodynamics, conversation of mass and thermodynamics properties table a numerical method has been developed to study fast filling process of natural gas vehicle’s (NGV) cylinder. The model has been applied for commonly cascade group of three reservoir tanks. The results indicated that there was a temperature rise in order 40 K or more during charging process. The results also indicated that ambient temperature has big effect on filling process and final NGV cylinder conditions.
