A fuel nozzle includes a swirler and a fuel injector positioned upstream from the swirler. The swirler includes an inner hub, an intermediate dividing wall, an outer shroud, a number of inner swirling vanes, and a number of outer swirling vanes. The intermediate dividing wall is concentrically positioned about the inner hub. The outer shroud is concentrically positioned about the intermediate dividing wall. Each inner swirling vane extends between the inner hub and the intermediate dividing wall, and each outer swirling vane extends between the intermediate dividing wall and the outer shroud. |
