Abstract: A combustor includes a housing and a liner that define an inlet configured to receive an inlet fluid. An inlet splitter is disposed in the inlet which splits the inlet into a first annulus and a second annulus. A fuel supply system selectively injects fuel into the first annulus and the second annulus, and a centerbody that includes a plurality of struts radially extending from a central hub receives the inlet fluid mixed with fuel, thereby creating fluid swirl.
