Abstract: The effects of four design parameters, the number of disks, the rotational frequency, the thickness of disk and the distance of two disks on noise generated from laminar flow fan were experimentally investigated, and discussed. The fan noise increases with increasing the number of disks and the rotational frequency. That is, the sound pressure is nearly proportional to the number of disks and the rotational frequency of the sixth power. The thickness of disk and the distance of two disks are little independenent of fan noise. According to specific noise level, the laminar flow fan is by no means inferior to the centrifugal fan. The laminar fan noise is almost turbulent noise.
