Embodiments of the disclosure include a combustor assembly. The combustor assembly may include one or more fuel plenums. The combustor assembly may also include one or more fuel distribution plates disposed within the fuel plenums. Moreover, the combustor assembly may include a number of mixing tubes disposed at least partially within the fuel plenums and extending through the fuel distribution plates. In certain aspects, the mixing tubes may each include a reduced diameter about the fuel distribution plates to form an annulus therebetween.
