Abstract
A cooling system for a gas turbine is disclosed comprising a vortex tube defining a body having an inlet port connectable to a compressor to receive compressed fluid. The vortex tube is configured to separate flow of the compressed fluid into a cold stream and a hot stream. The cooling system further includes a fluidic oscillator in fluid communication with the vortex tube, the first end of which is connected to a cold stream outlet port of the vortex tube to receive the cold stream. The fluidic oscillator is configured to generate at least two oscillator jets of the cold stream, operating at different oscillation frequencies, to produce biaxial pulsating flow oscillations onto a surface of at least one gas turbine blade of the gas turbine. A more efficient cooling system will result from the proposed cooling system's increased cooling impinging surface area and significantly reduced cooling fluid temperature differential.
