本篇論文旨在討論小型低速風洞建構後，於進行實驗前，需測試其風洞內部之風場情況，確實瞭解風場於試驗段穩定程度及其紊流強度能達到適當數值，使其相關實驗之成果將具備可信度；本校興建的風洞實驗室在目前階段於試驗段適當位置宜進行測量其風場流動情況，以探討本小型低速風洞中所呈現風場的實際情況，以為建構風洞之參考及改善風場之依據。

The goal of this research is to test the wind field conditions in the wind tunnel. Before the experiment, we have to understand the wind field's stability and turbulence intensity that reaches a proper value. These conditions will affect the reliability of the experiment results. At present stage, the wind tunnel in CYUT is under the testing of the wind flow conditions. This study reveals the exact wind field conditions. These will be the reference for constructing new wind tunnel and revising wind field conditions of the existed wind tunnels.
