The attached graph plots real data from a h2 refueller that is heavily reduced by a needle valve. The system cascade fills based on the differential between a large store to a smaller vehicle tank. The needle valve gives a system resistance co ‘K’ of approx. 5500 depending on opening.
Data is...
Hi all, thanks for reading.
I am trying to model the emptying of a pressurised gas body (e.g. tank/line) when a leak is present. I know the initial choked mass flow rate of the leak due to the internal pressure (350 bar), however, I am not sure how best to model the decreasing flow rate due to...
Hi, thanks for reading
I am a grad who is working in hydrogen refueling systems. I am working on analysis on potential leaks at the moment as its key these are properly assessed and managed when working with hydrogen, for obvious reasons.
Our system is storing compressed hydrogen at 500 bar...
