Abstract: An experimental investigation was made into the effects of four design parameters such as, (1) the number of disks, (2) the rotational frequency, (3) the thickness of disk, (4) the gap between two disks, on both noise and fluid dynamic characteristics. As a result, it is made cleared that the sound power is nearly proportional to the number of disks and the sixth power of the rotational frequency. The thickness of the disk and the gap between disks hardly affect the fan noise and relative velocity. The specific noise level of the laminar flow fan is comparable to that of the centrifugal fan. The noise generated from the laminar flow fan is almost controlled by turbulent noise.
