The CFD results confirmed that at each height above the lowest point of the rotor, the maximum value of the pressure around the tower shifted in the direction of the rotor rotation; this was caused by the diversion of air flow approaching the tower due to rotation of the blades. It was also confirmed that while a blade was passing upstream of the tower, the pressure fluctuations around the tower at each height above the lowest point of the rotor were greater on the side of the tower where the blade approaches than on the side where the blade moves away, due to the recovery of low pressure on the downstream side of the blade.

内容記述 | This study investigated the effects of the rotating blades of an upwind-type horizontal-axis wind turbine on the aerodynamic forces of the wind-turbine’s tower by conducting computational fluid dynamics (CFD) simulations of the flow around the wind turbine and its tower. The CFD results confirmed that at each height above the lowest point of the rotor, the maximum value of the pressure around the tower shifted in the direction of the rotor rotation; this was caused by the diversion of air flow approaching the tower due to rotation of the blades. It was also confirmed that while a blade was passing upstream of the tower, the pressure fluctuations around the tower at each height above the lowest point of the rotor were greater on the side of the tower where the blade approaches than on the side where the blade moves away, due to the recovery of low pressure on the downstream side of the blade. In addition, it was found out that while a blade was near the tower, the air pressure on the upwind side of the tower was reduced due to interference with the lower-pressure region on the downstream side of the blade. This interference caused a periodic decrease in the drag coefficient of the tower. Moreover, it was recognized that while a blade approached the tower and then moved away, the low-pressure region on the downwind side of the blade caused a drop in the pressure on the side of the tower adjacent to the blade. This pressure drop caused a periodic fluctuation in the side force coefficient of the tower. | |||||
