“…Some geometries appear to be less affected by that process, in which case ignition is more independent from the way the diaphragm bursts. This result differs from the literature [4][5][6], which states that in a longer tube, ignition is more probable at lower hydrogen pressure. This discrepancy will require further research, conducted with several tubes and with various types of diaphragm.…”

“…The difference between these two lines depends on the extension tube length, and is in the range of 1.5-11.5%. When compared with the results by Golub et al [4] and Mogi et al [6], the current experiments result in lower critical hydrogen pressure for given extension tube lengths.…”

“…An extension tube can be attached to the container. Extension tubes of various geometries have been tested in experimental and numerical investigations [4][5][6]. The extension tube tested in the current research consists of two parts: a first one, with diameter 10 and 10 mm long, placed immediately behind the diaphragm, and a second one connected to the first one, with various diameters and lengths.…”

The first investigations concerned with a problem of hydrogen jet ignition, during outflow from a high-pressure vessel were carried out nearly 40 years ago by Wolanski and Wojcicki. The research resulted from a dramatic accident in the Chorzow Chemical Plant Azoty, where the explosion of a synthesis gas made up of a mixture composed of three moles of hydrogen per mole of nitrogen, at 300 • C and 30 MPa killed four people. Initial investigation had excluded potential external ignition sources and the main aim of the research was to determine the cause of ignition. Hydrogen is currently considered as a potential fuel for various vehicles such as cars, trucks, buses, etc. Crucial safety issues are of potential concern, associated with the storage of hydrogen at a very high pressure. Indeed, the evidence obtained nearly 40 years ago shows that sudden rupture of a highpressure hydrogen storage tank or other component can result in ignition and potentially explosion. The aim of the present research is identification of the conditions under which hydrogen ignition occurs as a result of compression and heating of the air by the shock wave generated by discharge of high-pressure hydrogen. Experiments have been conducted using a facility constructed in the performed to determine critical conditions for occurrence of high-pressure hydrogen ignition. The results show that a critical pressure exists, leading to ignition, which depends mainly on the geometric configuration of the outflow system, such as tube diameter, and on the presence of obstacles.

“…In recent years one could observe an increased interest in hydrogen technologies and safety issues corresponding to them, including uncontrolled ignition during discharge into the air from high-pressure installations. Latest experimental [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] as well numerical [19][20][21][22][23][24] works focus mainly on the detailed description of the self-ignition mechanism according to different initial and boundary conditions including: extension channel geometry: diameter [4][5][6][7]19], length [5][6][7][8][9][10][11][12][13][14][15][16][17][20][21][22], cross-section shape [7,8,18,23] or obstacle presence in front of the hydrogen stream [18,…”

This paper demonstrates experimental and numerical study on spontaneous ignition of H 2 -N 2 mixtures during high-pressure release into the air through the tubes of various diameters and lengths. The mixtures included 5% and 10% (vol.) N 2 addition to hydrogen being at initial pressure in range of 4.3 -15.9 MPa. As a point of reference pure hydrogen release experiments were performed with use of the same experimental stand, experimental procedure and extension tubes. The results showed that N 2 addition may increase the initial pressure necessary to self-ignite the mixture as much as 2.12 or 2.85 -times for 5% and 10% N 2 addition respectively. Additionally, simulations were performed with use of Cantera code (0-D) based on the ideal shock tube assumption and with the modified KIVA3V code (2-D) to establish the main factors responsible for ignition and sustained combustion during the release.
