DNS of Lean Hydrogen Turbulent Premixed Flames at High Karlovitz Number Conditions (2020)
Conference Proceeding
Song, W., Hernandez Perez, F., Tingas, A., & Im, H. G. (2020). DNS of Lean Hydrogen Turbulent Premixed Flames at High Karlovitz Number Conditions. In AIAA Scitech 2020 Forum. https://doi.org/10.2514/6.2020-0917

To investigate the turbulent flame speed at high Karlovitz number (Ka) conditions, high fidelity direct numerical simulations (DNS) of lean hydrogen/air premixed flames propagating in a channel are performed with forced turbulence. The turbulent flame sp... Read More about DNS of Lean Hydrogen Turbulent Premixed Flames at High Karlovitz Number Conditions.

Computational investigation of rod-stabilized laminar premixed hydrogen–methane–air flames (2020)
Conference Proceeding
Hernandez Perez, F. E., Im, H. G., & Tingas, A. E. (2020). Computational investigation of rod-stabilized laminar premixed hydrogen–methane–air flames. In AIAA Scitech 2020 Forum. https://doi.org/10.2514/6.2020-1659

A computational study of steady, rod-stabilized, inverted, lean, CH4-air and H2-CH4-air flames is conducted. For the CH4-air flames, either decreasing the inlet equivalence ratio or increasing the mean inflow velocity leads to a larger standoff dista...
