| Abstract: | According to the sound radiation solution of rotating source in frequency domain,formulae of noise sources in turbomachine have been derived.Then the detailed aeroacoustic solutions of the sound field in the turbomachine,the blades of which are thin and bent slight in the mid-chord alignment were obtained.The result is suitable for near sound field analysis.Moreover the influence of geometric parameters and operation conditions are explicitly expressed in the frequency domain solutions. |
