Abstract

Tubular turbines have been widely used because of their good hydraulic performance and energy characteristics. During the operation of tubular turbine, the runner blades and guide vanes may be over-opened. This article uses computational fluid dynamics methods to numerically simulate the internal flow of a tubular water turbine under two operating conditions: the runner blades and guide vanes are over opened. Then, a comparative analysis was conducted on the effects of over opening of the impeller blades and guide vanes on the performance, internal flow rate, and energy loss of the unit. The research results show that when the runner blade is too open, the unit has a larger flow rate, but there will be a strong vortex in the outlet section, resulting in increased energy loss and low efficiency. When the guide vane is over opened, the unit has small flow rate, chaotic flow in the outlet section, small energy loss and high efficiency.
