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.
