Description

In this study, we performed a numerical study (LES) on the influence of separated flows from the wind turbine nacelle and tower on the wind turbine near wake region. As a result, when the tower part was made into a cylinder, a downward flow was induced behind the tower. It has become clear that as a result of this phenomenon, the wake region behind the wind turbine blades is also entrained toward the ground. In the future, we plan to change the size of the wind turbine tower and examine the above flow mechanism in detail.
