A nozzle includes a center body and a shroud circumferentially surrounding at least a portion of the center body to define an annular passage between the center body and the shroud. The nozzle further includes apertures through at least one of the center body or shroud, a plenum in fluid communication with the apertures, and a louvers proximate to the apertures and connected to at least one of the center body or shroud. A method for cooling a nozzle includes flowing a cooling medium through a plenum inside a center body of the nozzle and flowing the cooling medium through apertures in the center body. The method further includes redirecting the cooling medium with louvers to flow the cooling medium across a surface of the center body.
