XiFoamを用いて球状に膨張する水素-空気予混合火炎の挙動を調べるために二次元および三次元シミュレーションを行った。当量比は1.0に設定した。着火は分域の中心から始まり、火炎は球状に膨張してしわになった。得られた火炎半径は実験結果と一致した。

We performed the two- and three-dimensional simulations to investigate the behavior of spherically expanding H$$_{2}$$-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.
