Threedimensional jet issuing from the cruciform nozzle. II  Turbulence properties.
Abstract
Detailed measurements of turbulence quantities in a threedimensional jet issuing from a cruciform nozzle have been made in order to investigate the similarity of each turbulent profile and the streamwise development of the characteristic 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 equal to or greater than 100. The Reynolds number based on the velocity scale and the length scale is constant, so the present turbulent jet remains steady.
