Wind Speed Test
 

Most human activity is near the earth's surface, which is influenced by the lowest part of the atmosphere called the planetary boundary layer (PBL), also known as the atmospheric boundary layer (ABL) or peplosphere. In addition, Taiwan's northern part and offshore islands receive constant northeast seasonal winds for about eight months per year.

This is a strong source of wind energy, so there is potential to develop local energy source. Generally, there are three methods of analyzing wind fields: (1) on-the-spot measurements, (2) calculations based on hydrodynamics theory and analysis, and (3) indoor wind tunnel simulation. Wind tunnel testing is essential in wind field structure and wind engineering research, because it can be manipulated better, be reproducible, and simulate complex situations.

This test utilizes a LWT46 low wind tunnel, which is 2.765m(L)x1.824m(W)x1.122m(H) and wind speed up to 70m/s.
