1. A method for cooling a compressor section of a gas turbine engine, the method comprising:
sensing, via at least one first temperature sensor, a first temperature at a first location on a stationary assembly of the compressor section;
sensing, via at least one second temperature sensor, a second temperature at a second location on the stationary assembly of the compressor section, the second location spaced apart from the first location;
determining, via a controller, a delta between the first temperature and the second temperature;
operating, via the controller, at least one cooling element when the delta exceeds a predetermined threshold, the at least one cooling element provided at the first location of the stationary assembly of the compressor section;
repeating sensing, via the at least one first temperature sensor, the first temperature at the first location on the stationary assembly of the compressor section;
repeating sensing, via at least one second temperature sensor, the second temperature at the second location on the stationary assembly of the compressor section;
repeating determining, via the controller, the delta between the first temperature and the second temperature; and
repeating operating, via the controller, the at least one cooling element when the delta exceeds the predetermined threshold, wherein repeating operating of the at least one cooling element when the delta exceeds the predetermined threshold further comprises:
continuously receiving, via the controller, the first and second temperatures; and
maintaining the delta between the first temperature and the second temperature within prescribed limits to mitigate deformation of a rotating assembly of the compressor section, the deformation of the rotating assembly being a bowing effect.
