The Propagation Characteristics of Turbulent Expanding Flames of Methane/Hydrogen Blending Gas by Haoran Zhao, Chunmiao Yuan, Gang Li, Fuchao Tian

“…The turbulent burning velocities of methane/hydrogen mixture are determined over a wide range of hydrogen fractions, and four classical unified scaling models (the Zimont model, Gulder model, Schmidt model, and Peters model) are evaluated by the experimental data. The acceleration onset, cellular structure, and acceleration exponent of turbulent expanding flames are determined, and an empirical model of turbulent flame acceleration is proposed. …”
