Abstract: The effects of three parameters, such as the combination of the number of blades of a front rotor and a rear rotor, the solidity and the blade tip clearance, on both the fluid dynamic and noise characteristics were experimentally investigated. As a result it was concluded that the noise due to the interaction between the front rotor and the rear rotor blades can be reduced if the combination of the number of two rotor blades is well selected. When the solidity of the two rotors was the same, the total pressure coefficient became high and the specific noise level low. The smaller the tip clearance was, the higher the fan efficiency and the total pressure coefficient were.
