Cross-scale turbulent kinetic energy transfer in the presence of coherent structures in premixed swirl combustion
Askar Kazbekov, Adam M. Steinberg
This paper experimentally analyzes the simultaneous influence of heat release and coherent vortex structures on the transfer of kinetic energy across scales around the laminar flam…
Experimental Study of Forced Synchronization and Cross-coupling in a Liquid-Fuelled Gas Turbine Combustor at Elevated Pressure
Mitchell L. Passarelli, Askar Kazbekov, Victor Salazar +2
The effects of external forcing on a turbulent, liquid-fuelled, swirl-stabilized gas turbine combustor operating at a pressure of approximately 1 MPa are explored experimentally. I…
Cross-Frequency Coupling During Thermoacoustic Oscillations in a Pressurized Aeronautical Gas Turbine Model Combustor
Mitchell L. Passarelli, Timothy M. Wabel, Arin Cross +2
This paper demonstrates cross-frequency coupling between pressure, heat release rate, fuel spray and velocity oscillations in a model aeronautical gas turbine combustor operating a…
Flame- and flow-conditioned vorticity transport in premixed swirl combustion
Askar Kazbekov, Adam M. Steinberg
This paper presents an experimental analysis of flame-induced enstrophy transport in premixed swirl combustion at Karlovitz numbers between 20-50. Such flames posses a large-scale…
Using machine learning to construct velocity fields from OH-PLIF images
Shivam Barwey, Malik Hassanaly, Venkat Raman +1
This work utilizes data-driven methods to morph a series of time-resolved experimental OH-PLIF images into corresponding three-component planar PIV fields in the closed domain of a…
Experimental Data Based Reduced Order Model for Analysis and Prediction of Flame Transition in Gas Turbine Combustors
Shivam Barwey, Malik Hassanaly, Qiang An +2
In lean premixed combustors, flame stabilization is an important operational concern that can affect efficiency, robustness and pollutant formation. The focus of this paper is on f…
