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’...

In some instances, it is inevitable that large amounts of potentially hazardous chemicals like chlorine gas are stored and used in facilities in densely populated areas. In such cases, all safety issues must be carefully considered. To reach this goal, it is important to have accurate information concerning chlorine gas behaviors and how it is dispersed in dense urban areas. Furthermore, mainta...
