A solar updraft tower is one of the wind power generation plants which utilizes solar energy. The purpose of this study was to ascertain whether the tower was also able to utilize crosswind energy. Wind tunnel experiments and numerical simulations were conducted simulating the crosswind. The results showed that suctioned updraft speed in the tower was proportional to the crosswind speed, and its conversion rate depended on the tower configuration. A diffuser-shaped tower with a vortex generator achieved to produce the updraft whose speed exceeded the crosswind speed. It was due to the low pressure created by the vortex atop the tower and to the diffuser effect. The crosswind utilization enables the simple power generation device to generate electricity during the night, and the hybrid utilization of renewable energies contributes to the increasing wind energy market.

被忽视的风能产生更多的电力：太阳能上升塔到风能太阳能塔

太阳能上升气流塔是利用太阳能的风力发电厂之一。这项研究的目的是确定该塔是否也能够利用侧风能。进行了模拟侧风的风洞实验和数值模拟。结果表明，塔内吸入的上升气流速度与侧风速度成正比，其转化率取决于塔的配置。带有涡流发生器的扩散器形塔可产生速度超过侧风速度的上升气流。这是由于塔顶的涡流和扩散器效应产生的低压。侧风利用使简易发电装置在夜间发电，
