Direct numerical simulation (DNS) is used to study reacting, laminar vortex rings. A novel, all-Mach number algorithm developed by Doom, Hou, & Mahesh1 is used. The chemical mechanism is a nine species, nineteen reaction mechanism for H2/Air from Mueller at el.2 Diluted H2 at ambient temperature (300 K) is injected into hot air (1200 K & 1800 K). The simulations study the effect of Damkohler number, initial oxidizer temperature and stroke length.
