Direct Numerical Simulation of hydrogen combustion at auto-ignitive conditions: Ignition, stability and turbulent reaction-front velocity
Gruber, Andrea; Bothien, Mirko R.; Ciani, Andrea Camperio; Aditya, Konduri; Chen, Jacqueline H.; Williams, Forman Arthur (Peer reviewed; Journal article, 2021)Direct Numerical Simulations (DNS) are performed to investigate the process of spontaneous ignition of hydrogen flames at laminar, turbulent, adiabatic and non-adiabatic conditions. Mixtures of hydrogen and vitiated air ... -
Direct numerical simulations of premixed and stratified flame propagation in turbulent channel flow
Gruber, Andrea; Richardson, Edward S.; Aditya, Konduri; Chen, Jacqueline H. (Journal article; Peer reviewed, 2018)Direct numerical simulations are performed to investigate the transient upstream flame propagation (flashback) through homogeneous and fuel-stratified hydrogen-air mixtures transported in fully developed turbulent channel ... -
The effect of pressure on lean premixed hydrogen-air flames
Rieth, Martin; Gruber, Andrea; Chen, Jacqueline H. (Journal article; Peer reviewed, 2023)The effect of pressure on the propagation of lean premixed hydrogen-air flames is investigated numerically with a hierarchy of canonical configurations including direct numerical simulations of turbulent flames in homogeneous ...
