Abstract
An experimental study was made to clarify the fundamental flow characteristics of Sirocco fans. Using fan's height is 115mm, inlet radius is 80mm, outlet radius is 90mm, vane angle is 150 degree, number of vanes is 52. This fan rotates with 23.75Hz. The oscillations of the radial velocity in the sirocco fan installed in the open space were measured by the hot wire probe. By FFT analysis, the two magnitude peaks of the radial velocity were found and the two significant peaks were found. The first peak was found at 19Hz and has the three cells rotating with the rotation of the impeller. The second peak was found at 33Hz and has the four cells rotating with the rotation of the impeller.
