Studies on a Wells Turbine for a Wave Power Generator : 5th Report, On Some Factors Concerning the Stall Condition

Abstract

Factors determining stall conditions of a Wells turbine were discussed from the viewpoint of design. Experimental investigations were performed to study the effect of the inlet flow turbulence and the setting position of the blade axis on the performance of the Wells turbine. It is concluded that due to the peculiar nature of the Wells turbine the performance is less sensitive to the inlet flow turbulence and more sensitive to the setting axis of the airfoil on the rotor.
