摘要

本研究探讨了在朝前的台阶上安装萨沃尼水轮机以提高动力效率的效果。由于水流受到台阶的干扰，涡轮机可以从台阶顶部的加速水流中获益。在三维计算域中使用计算流体力学对流场进行求解。有限体积法用于求解雷诺平均纳维-斯托克斯控制方程和 SST k-ω 湍流方程。该模拟包括旋转涡轮机和台阶。这项工作的新颖之处在于研究了以幂律风速分布作为入口速度的这种配置，这在常见应用中更为现实，同时还研究了不同的涡轮机。研究结果表明，当萨沃尼斯涡轮机安装在 5 米台阶上时，其发电量最多可增加 73%。然而，如果台阶很高，或采用不同的涡轮机，则没有观察到任何改进。

Performance of a Savonius Vertical Axis Wind Turbine installed on a Forward Facing Step

This study investigates the effects of installing a Savonius turbine on a forward-facing step to increase the power efficiency. Since the flow is disturbed by the step, the turbine may benefit from the accelerated flow found on top of the step. The flow field is solved using Computational Fluid Dynamics in a 3D computational domain. The Finite Volume Method is used to solve the Reynolds Average Navier-Stokes governing equations and the SST k-ω turbulence equations. This simulation includes both rotating turbine and the step. The novelty of this work is to study this configuration with a power law wind velocity distribution as inlet velocity, which is more realistic in common applications, and to investigate a different turbine. The study shows that the Savonius turbine generates up to 73% more power when installed on a 5-meter step. However, in case of a very high step, or a different turbine no improvement has been observed.
