Flame-wall interaction of thermodiffusively unstable hydrogen/air flames -- Part II: Parametric variations of equivalence ratio, temperature, and pressure
Max Schneider, Hendrik Nicolai, Vinzenz Schuh +2
Fuel-lean hydrogen combustion systems hold significant potential for low pollutant emissions, but are also susceptible to intrinsic combustion instabilities. While most research on…
Flame-wall interaction of thermodiffusively unstable hydrogen/air flames -- Part I: Characterization of governing physical phenomena
Max Schneider, Hendrik Nicolai, Vinzenz Schuh +2
Hydrogen combustion systems operated under fuel-lean conditions offer great potential for low emissions. However, these operating conditions are also susceptible to intrinsic therm…
Assessment of flamelet manifolds for turbulent flame-wall interactions in Large-Eddy Simulations
Yujuan Luo, Matthias Steinhausen, Driss Kaddar +2
A turbulent side-wall quenching (SWQ) flame in a fully developed channel flow is studied using Large-Eddy Simulation (LES) with a tabulated chemistry approach. Three different flam…
Application of dense neural networks for manifold-based modeling of flame-wall interactions
Julian Bissantz, Jeremy Karpowski, Matthias Steinhausen +5
Artifical neural networks (ANNs) are universal approximators capable of learning any correlation between arbitrary input data with corresponding outputs, which can also be exploite…
