A Novel Approach for Direct Measurement of the Stretch Factor in Laminar Premixed Hydrogen-Air Flames Affected by Thermodiffusive Instabilities
Marcel Marburger, Christoph Möller, Andrew MacFarlane +5
This study introduces a novel experimental configuration using OH-PLIF imaging to directly determine the stretch factor () in laminar premixed hydrogen flames transitioning fr…
Direct numerical simulation of thermo-diffusively unstable premixed hydrogen-air flames in a fully-developed turbulent channel flow at
Felix Rong, Max Schneider, Hendrik Nicolai +2
Direct Numerical Simulations (DNS) of premixed hydrogen-air flames anchored in a fully-developed turbulent channel flow (TCF) are performed at a friction Reynolds number of $\mathr…
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…
