A Bladeless fan is a novel type of fan with an unusual geometry and unique characteristics. This type of fan has been recently developed for domestic applications in sizes typically up to 30cm diameter. In the present study, a Bladeless fan with a diameter of 60cm was designed and constructed, in order to investigate feasibility of its usage in various industries with large dimensions. Firstly, flow field passed through this fan was studied by 3D modelling. Aerodynamic and aero acoustic

Moreover, the experimental results in the present study showed that this fan is capable to be designed and used for various industrial applications. A bladeless fan blows air from a ring with no external blades. The air is drawn by a compressor in the base and directed up into a ring. The fan contains a electric brushless motor and this motor rotates blades that are attached with the rotor. Usually the upper frame of this fan is a ring shaped. The air flows through the channel in the pedestal of the fan when the motor is turned on.
