Uncovering flame physics with machine learning: application to the reaction rate in hydrogen flames
Antonio Attili, Ludovico Nista, Tommaso Baffetti +6
Convolutional Neural Networks (CNNs) are used as analytical tools to investigate the relationship between the progress variable field and the local chemical source term in lean pre…
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…
Comprehensive linear stability analysis for intrinsic instabilities in premixed ammonia/hydrogen/air flames
Terence Lehmann, Lukas Berger, Thomas L. Howarth +4
Two-dimensional direct numerical simulations of planar laminar premixed ammonia/hydrogen/air flames are conducted for a wide range of equivalence ratios, hydrogen () fract…
Thermodiffusively unstable laminar hydrogen flame in a sufficiently large 3D computational domain -- Part I: Characteristic patterns
Wen Xu, Berger Lukas, Cai Liming +2
Thermodiffusive instabilities can have a leading order effect on flame propagation for lean premixed hydrogen flames. Many simulation studies have been performed to study this effe…
Efficient and accurate calculation of dispersion relations for intrinsically unstable premixed flames
Sofiane Al Kassar, Lukas Berger, Pasquale E. Lapenna +3
Premixed flames are susceptible to hydrodynamic and thermodiffusive instabilities that wrinkle the flame front and lead to complex multiscale patterns. They strongly impact the fla…
