Hi All, I have tried to simulate in a simplified way a "gaseous hydrogen cylinders filling operation", where the process stream is pure hydrogen, compressed by a positive displacement compressor at constant flow rate of 32.5 kg/h and loaded into a cylinders bundle. The system (compressor discharge piping and cylinders bundle) is initially at 10 bar(g) and 30C, following pressure equalization. As the cylinders are made of composite material, with a max admissible temperature of 85C, I want to model...
