Performance of vertical axis water turbine with eye-shaped baffle for pico hydropower
文献摘要：
A series of inline pico hydropower systems,which could be used in confined space,especially for water distribution networks(WDNs),was designed and investi-gated.The turbine with an eye-shaped vertical water baffle was developed to evaluate the hydraulic performance.A three-dimensional dynamic mesh was employed and the inlet velocity was considered as the inlet boundary condition,whereas the outlet boundary was set as the outflow.Then,numerical simulations were conducted and the standard k-ε turbulence model was found to be the best capable of predicting flow features through the comparison with the experimental results.The effects of the opening diameter of the water baffle and installation angle of the rotor on the flow field in the turbine were investigated.The results suggested that the water baffle opening at d=30 mm and the rotor at a 52° angle could achieve the highest efficiency of 5.93％.The proper eye-shaped baffle not only accelerates the fluid flow and generates positive hydro-dynamic torque,but also eliminates the flow separation.The scheme proposed in this paper can be exploited for practical applications in the water pipelines at various conditions and power requirements.
