Computation and prediction of intrinsic thermoacoustic oscillations associated with autoignition fronts
Gopalakrishnan, Harish Subramanian; Gruber, Andrea; Moeck, Jonas (Peer reviewed; Journal article, 2023)A sequential combustor architecture consists of two longitudinally staged combustion zones featuring a propagation-stabilized flame in the first stage and an autoignition-stabilized flame in the second (reheat) stage. This ... -
Computation of Intrinsic Instability and Sound Generation From Autoignition Fronts
Gopalakrishnan, Harish Subramanian; Gruber, Andrea; Moeck, Jonas (Peer reviewed; Journal article, 2022)Burning carbon-free fuels such as hydrogen in gas turbines promise power generation with minimal emissions of greenhouse gases. A two-stage sequential combustor architecture with a propagation-stabilized flame in the first ... -
Dynamics and stability of autoignition fronts in elementary reheat combustor configurations
Gopalakrishnan, Harish Subramanian (Doctoral theses at NTNU;2022:371, Doctoral thesis, 2022)Stringent regulations on greenhouse gas emissions from gas turbines used for land-based and aircraft applications has resulted in a gradual transition towards carbon-free fuels such as hydrogen. Conventional single-stage ... -
Response of Autoignition-Stabilized Flames to One-Dimensional Disturbances: Intrinsic Response
Gopalakrishnan, Harish Subramanian; Gruber, Andrea; Moeck, Jonas (Peer reviewed; Journal article, 2021)Burning carbon-free fuels such as hydrogen in gas turbines promises power generation with strongly reduced greenhouse gas emissions. A two-stage combustor architecture with a propagation-stabilized flame in the first stage ...
