Development and validation study of a 1D analytical model for the response of reheat flames to entropy waves
Gant, Francesco; Gruber, Andrea; Bothien, Mirko R. (Peer reviewed; Journal article, 2020)Numerical simulations of laminar premixed flames burning hydrogen and methane in spontaneous ignition mode are performed by harmonically exciting the reactants’ temperature at the domain inlet. The results are compared to ... -
Direct numerical simulation of flame stabilization assisted by autoignition in a reheat gas turbine combustor
Aditya, Konduri; Gruber, Andrea; Xu, Chao; Lu, Tianfeng F.; Krisman, Alex; Bothien, Mirko R.; Chen, Jacqueline H. (Journal article; Peer reviewed, 2018)A three-dimensional direct numerical simulation (DNS) is performed for a turbulent hydrogen-air flame, represented with detailed chemistry, stabilized in a model gas-turbine combustor. The combustor geometry consists of a ... -
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 ... -
The effect of hydrogen enrichment, flame-flame interaction, confinement, and asymmetry on the acoustic response of a model can combustor
Æsøy, Eirik; Indlekofer, Thomas; Gant, Francesco; Cuquel, Alexis; Bothien, Mirko R.; Dawson, James Richard (Peer reviewed; Journal article, 2022) -
A skeletal mechanism for prediction of ignition delay times and laminar premixed flame velocities of hydrogen-methane mixtures under gas turbine conditions
Jiang, Yuanjie; del Alamo Serrano, Gonzalo; Gruber, Andrea; Bothien, Mirko R.; Seshadri, Kalyanasundaram; Williams, Forman Arthur (Peer reviewed; Journal article, 2019)The aim of this study is to eliminate unimportant steps from a detailed chemical-kinetic mechanism in order to identify a skeletal kinetic mechanism that can predict with sufficient accuracy ignition delay times and laminar ...
