Cryogenic installations of superconducting accelerators contain significant amount of high density helium, mostly filling the cryostats and headers located in underground tunnels and caverns. In the case of emergency relief of the helium, oxygen deficiency hazard arises. The paper proposes a description of helium–air mixture formation based on turbulent jet physics. A condition of stratified flow...
