| 内容記述 | Turbulence properties of a bounded jet flow, such as the turbulence intensity in streamwise, transverse and spanwise directions, the turbulence energy, the Reynolds stress and the production term of turbulence energy, are measured in the mid-plane of a bounded jet flow and in the planes parallel to this plane, by using the rectangular nozzle whose aspect ratio is 2. The variations of these turbulence properties both in transverse direction and in spanwise direction are discussed, as compared to those in the initial mixing region of a two-dimensional jet flow. It has been found that the turbulence intensity in the transverse direction is independent of the existence of the bounding plates and that the variations of the streamwise turbulence intensity correspond to those of the production term of turbulence energy. Furthermore, at a certain downstream location from the nozzle exit, the mean flow and turbulence properties in the cross section normal to streamwise direction are also investigated. The secondary flow and the streamwise vorticity have been obtained by measuring the mean velocity components in transverse and spanwise directions. The contour lines of the turbulence intensity, the Reynolds stress and the vorticity have been obtained. Turbulence properties of a bounded jet flow are clarified by using these results. |
