Rotational speeds of over 26,000r.p.m. have been measured for a disc-windmill in an airflow of 45m/sec. at zero fluid flow rate; normal operating conditions are between one third and one half of this rotational speed. Figure 2 shows schematically the extremely simple form of the disc-windmill atomiser.

WebA vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair. VAWTs do not need to be pointed into the wind, which …
