 note = {We made an experimental and a theoretical investigation on the turbulent noise generated by a bladed multiple-disk fan. In the theory, we assumed that the turbulent noise consists of two sources: the turbulence of boundary layer on the disk surface and the vortex shedding from the trailing edge of the blades, and that these two sources are independent of each other. To estimate the acoustic power due to the latter source, we proposed a new method to calculate the wake width which is an important parameter to control the noise level. The effects of the four parameters: the span length of the blade, the number of blades, the inner radius of the impeller and the setting angle of the blade, on the turbulent noise were investigated. The agreement between the theoretical and the experimental results was satisfactory., 日本機械学會論文集. B編 62(596) p.1420-1427 1996},
