摘要： A system for thermal management of exhaust gas includes: a nozzle configured to be disposed in fluid communication with an exhaust of a turbomachine; a mixing conduit in fluid communication with the nozzle; at least one secondary inlet disposed around a periphery of the nozzle and extending between an exterior of the mixing conduit and an interior of the mixing conduit; a variable nozzle mechanism configured to be movable between i) a first position in which the mechanism is configured to close the at least one secondary inlet and ii) a second position in which the mechanism is configured to open the at least one secondary inlet and adjust a selected diameter of the nozzle; and an actuator configured to move the variable nozzle mechanism between the first position and the second position.

摘要： An exhaust stack having a junction tube and a flue is provided. The flue has a silencer portion, a converging duct portion, a tubular portion, and a diverging diffuser portion. The silencer portion fluidly communicates with the junction tube. The silencer portion has a first hydraulic mean cross-sectional flow path, and the tubular portion has a second hydraulic mean cross-sectional flow path less than or equal to the first hydraulic mean cross-sectional flow path. The converging duct portion is coupled between the silencer portion and the tubular portion. The diverging diffuser portion is coupled to an end of the tubular portion opposite to the converging duct portion, such that exhaust gases flowing through the junction tube, the silencer portion, the converging duct portion, the tubular portion and the diverging diffuser portion have a reduced overall pressure drop, at least in part due to the diverging diffuser portion and the second hydraulic mean cross-sectional flow path being less than or equal to the first hydraulic mean cross-sectional flow path.
摘要翻译：提供具有连接管和烟道的废气堆。烟道具有消音器部分，会聚管道部分，管状部分和发散扩散部分。消声器部分与连接管流体连通。消音器部分具有第一液压平均横截面流动路径，并且管状部分具有小于或等于第一液压平均横截面流动路径的第二液压平均横截面流动路径。会聚管道部分联接在消音器部分和管状部分之间。发散扩散器部分连接到与会聚管道部分相对的管状部分的端部，使得流过连接管，消声器部分，会聚管道部分，管状部分和发散扩散部分的废气具有减小的至少部分地由于扩散部扩散部分和第二液压平均截面流动路径小于或等于第一液压平均横截面流动路径的整体压降。
