Abstract: A combined water-wash and water injection cooling system for a gas turbine engine including a water delivery system, an air delivery system, and a controller configured to couple to the gas turbine engine, the water delivery system, and the air delivery system to access and execute one or more routines. The water delivery system includes one or more spray nozzles to spray water upstream and directly in front of a compressor of the gas turbine engine. The air delivery system is configured to provide air from the compressor to the water delivery system so that the one or more spray nozzles spray atomized water into the compressor of the gas turbine engine during a cooling mode to cool the compressor. During an on-line water wash mode, air from the air delivery system to the water delivery system is turned off to enable the one or more spray nozzles to spray non-atomized water into the compressor of the gas turbine engine to wash the compressor.

Abstract: Systems are provided that may be used to diffuse and deflect the flows of gas into a plurality of gas flows. A gas flow, for example, exhaust gas, may be diffused, that is, spread out by the diffuser. A flow deflector may be coupled to the diffuser so that the gas flow may result in a plurality of gas flows. By diffusing and allowing a plurality of gas flows, improved gas flows may be achieved.
