Numerical Steady and Transient Evaluation of a Confined Swirl Stabilized Burner
International Journal of Turbomachinery, Propulsion and Power, 2021 Lean premixed combustion technology became state of the art in recent heavy-duty gas turbines and aeroengines. In combustion chambers operating under fuel-lean conditions, unsteady heat release can augment pressure amplitudes, resulting in component ...
