<p>A turbomachine includes a compressor, a turbine, a combustor operatively coupled to the compressor and the turbine, and an injection nozzle assembly (38) mounted in the combustor. The injection nozzle assembly (38,39) includes a swirler member (74) for conditioning a fluid flow passing through the injection nozzle assembly (38,39). The swirler member (74) includes a hub portion (84), a plurality of vanes (86) that extend from the hub portion (84), and at least one flow conditioning band (94,95). The at least one flow conditioning band (94,95) extends about the hub portion (84) and between the plurality of vanes (86) to provide a localized flow impediment within the injection nozzle assembly (38,39).</p> |
