Effect of Modulation of the Inlet Velocity and Equivalence Ratio Gradients on the Stabilization of Stratified Axisymmetric Bluff-Body Flames

<div>Simulated volume integrated, flame zone heat release (Q) and afterbody exit, and area-weighted equivalence ratio (Φ) time series together with their respective spectral densities at the three forcing frequencies of (a, d, g) 50 Hz, (b, e, h) 100 Hz, and (c, f, i) 200 Hz.</div>
