Default CNG Fast Filling in a Cylinder
Posts: n/a
Hello, I am an undergraduate student and working on finding out temperature distribution in and outside of cylinder during fast filling with compressed natural gas. I have meshed the model in Gambit and trying to simulate the 2D axysymmetric flow in Fluent. I have meshed the outer ambient area too to have convection heat transfer in order to find out what happens if I put some water circulation outside. I am setting mass flux with an UDF and selecting k-epsilon RMG model. The boundaries of the cylinder are walls. I am not sure whether I am proceeding in the right path to solve my problem. Could you help me with you suggestions.

Thank you
