概要

• 論文の詳細を見る

• Detailed measurements of turbulence quantities in a three-dimensional jet issuing form the cruciform nozzle have been made in order to investigate the similarity of each turbulent profile and the streamwise development of the characteristics scales. Experimental results are summarized as follows: Up to far downstream, the decay rate of turbulent velocity scales is slower than that of mean velocity scale, and the pertinent properties such as three components of turbulent intensity and Reynolds shear stress are similar in the extent of x/d≧100. The Reynolds number based on the velocity scale Uox and the length scale b' is constant, so the present turbulent jet remains steady.
