摘要

This paper is focus on design, building and calibrating a small open circuit wind tunnel and measuring turbulent characteristic of flow such as kurtosis, skewness, standard deviation, turbulence intensity and variance of flow by hot wire anemometer and dependence of them on velocity and screen meshes and honey comb in the wind tunnel. This wind tunnel specially built for stability and transition studying around rotating bodies, so we built a smoke generator in order to show the transition region on the boundary layer of models. This paper includes some pictures that were made by flow visualization on rotating bodies. In this paper we also measure pressure coefficient around a cylinder and drag coefficient around a sphere and compare our result by some another same experiments, also we visualize flow around sphere in Reynolds 11500.
