| Abstract: | It is experimentally demonstrated that the efflux of hydrogen at a high pressure into air via a nozzle array is accompanied
by the interaction of jets, which results in the conditions for self-ignition at a nozzle diameter below the values for which
self-ignition is possible in a single jet. Conditions for the safe efflux of hydrogen via a nozzle array from a reservoir
at a pressure of 400 bar (and below) are established. |
