This paper presents the modeling of low-concentration hydrogen deflagrations performed with the recently developed KYLCOM model. Three experiments carried out in THAI facility (performed in the frames of international OECD THAI experimental program) were selected for the simulation exercise. The tests allow studying lean mixture hydrogen combustion at normal ambient, elevated temperature and su...
