We performed the two- and three-dimensional simulations to investigate the behavior of spherically expanding H₂-air premixed flame by using XiFoam. The equivalence ratio was set to unity. The ignition started from the center of domain, and the flame expanded spherically and became wrinkle. The obtained flame radius has the agreement with the experimental result.
