Guide vanes are installed in the Wells turbine in order to improve the performance such as efficiency, self-rotating characteristics and off-design one with stall. This paper tries to make clear the roles of guide vanes for turbine systems with the simple momentum theory. It is found that the upstream guide vanes are more effective for the efficiency than the downstream guide vanes. The guide vanes are designed by using experimental data from the rotor without guide vane and potential flow calculation around guide vane. Experimental investigations on the effect of the guide vanes for the performance of Wells turbine are carried out and rearranged to confirm the momentum theory proposed in this paper.read more
