Abstract

The effects of a cylindrical contraction, consisting of two half cylinders installed next to the side walls of a wind tunnel and a full cylinder in between, on the distortion of a turbulent flow were experimentally investigated. The cylinders were 15.2 cm (6 in) in diameter and 76.2 cm (30 in) in height installed in a closed loop wind tunnel with a 76.2 cm by 76.2 cm (30 in by 30 in) cross section. Turbulent flow was generated by means of a perforated plate situated at the entrance of the wind tunnel. The nominal flow velocity was fixed at 5 m/s, 6.5 m/s and 8.5 m/s, resulting in Reynolds numbers of 12,000, 17,000 and 22,000 based on the diameter of the perforated plate holes (d =3.8 cm). A hot-wire anemometry unit was used to measure both distorted and undistorted turbulent flows at a 15.2 cm (6 in) by 15.2 cm square plane. (Abstract shortened by UMI.)
