In situ foam generation within a turbine engine

A foam generating assembly for a turbine system, comprising:

• an aerating gas hose extending through a port of the turbine system;
• a water-based liquid detergent hose extending through the port;
• and
• an in situ foam generating device having a maximum width sized to pass through a minimum width of the port, wherein the in situ foam generating device is positioned within a fluid passageway of the turbine system such that the in situ foam generating device generates foam within the fluid passageway and outputs the foam directly into the fluid passageway, wherein the in situ foam generating device is coupled to the aerating gas hose through which an aerating gas is received by a first fluid path of the in situ foam generating device, wherein the in situ foam generating device is coupled to the water-based liquid detergent hose through which a water-based liquid foaming detergent is received by a second fluid path separate from the first fluid path, the second fluid path concentric with the first fluid path, wherein the in situ foam generating device comprises a body having a first end, a second end, and an outer wall comprising the maximum width of the in situ foam generating device and extending from the first end to the second end, and wherein the aerating gas hose and the water-based liquid detergent hose are coupled to the first end inward from the maximum width of the outer wall.
