摘要
得到中弧线小弯度薄叶片叶轮机械声场的详细结果。讨论适用于近声场，叶片的弯、掠等几何特征及运行条件也都在频域解中显式地表示出来。
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.
