1702 Study of efficient sirocco fan using contra-rotating rotors
Details
A sirocco fan using contra-rotating rotors was proposed for the purpose of higher pressure and more compact structure of sirocco fan. If the high discharge pressure is obtained with the adoption of the contra-rotating rotors, it could be used for various purposes. Pressure coefficient of a sirocco fan with contra-rotating rotors is higher than that of conventional sirocco fan which is 2.5 times of conventional one.
