Wrinkle behavior of H₂-air premixed flame inside of a vessel was numerically investigated with changing mesh size of 2.0mm to 0.625mm by using the open source code, XiFoam. When the mesh size was smaller, larger number of ignition cells was obtained and wrinkle flame formation was observed, and then flame temperature heightened and flame radius became large.
