The northwest region of China’s loess plateau is an important area for wind power development. However, the unclear understanding evolution mechanism near-ground atmospheric boundary layer (ABL), which influenced by its unique geomorphological features, has compromised safety and stability turbine operations. To address this challenge, tunnel experiments were conducted to investigate mean turbulent characteristics wake flow generated mountains in plateau. results indicate that terrain...
In order to investigate the impact of flow field on wind turbine power in northwest China’s Loess Plateau, a tunnel experiment was conducted using self-designed model that simulated actual terrain. By comparing experiments utilizing an ideal mountain under varying incoming speeds, it revealed Plateau terrain resulted increased inflow speed for turbine. This higher led approximate 5% increase output but also caused about 6.1% rise fluctuations. Through analysis spectrum output, discovered...
Considering its Venturi effect, long corridor terrain is considered as one of the outstanding wind-energy resources, but has not been developed due to unclear inflow turbulence effects on wind turbines.
