摘要

To improve turbine efficiency at low-speed flow, the computational fluid dynamics software Fluent was used to simulate numerically the blades designed to work at low speed flow for researching the effect of tip speed ratio on the power characteristics and flow field characteristics of low-speed turbine blades. The simulation results show that the tip speed ratio not only affects the flow field around the blade, but also has a certain effect on the wake field of the turbine, and the smaller the tip speed ratio is, the faster the wake field recovers.
