Performance of the Wells Turbine with a Double Row of Guide Vanes
The paper describes a theoretical and experimental investigation concerning the aerodynamic performance of the Wells turbine, in which a stationary blade row is added on each side of the rotor. The entire blade system is symmetrical with respect to a plane perpendicular to the turbine axis. A quasi-three-dimensional flow analysis is developed and used to design and build a turbine model. Experimental as well as theoretically predicted values are presented and indicate that the presence of stationary blades can provide a considerable increase in efficiency.
