A thermally diffusively unstable, spherically expanding H₂-air flame is shown. Intrinsic instabilities lead to strongly corrugated flame fronts which increase both the flame surface area and the burning rate. However, these flames are characterized by low pollutant emissions. Therefore, understanding the dynamics of lean H₂-air flames is of utmost importance for the safe operation of technical combustion chambers.
