Scaling Laws for Thermodiffusively Unstable Lean Premixed Turbulent Hydrogen-Air Flames
M. Gauding T. Lehmann, T. L. Howarth, L. Berger +9
Lean premixed hydrogen-air flames are strongly affected by thermodiffusive (TD) instabilities, which can alter the flame structure and enhance the local reactivity many-fold. Two r…
