Turbulent properties of two-dimensional turbulent wall jet

Measurements of fluctuating properties of two-dimensional turbulent wall jet without an external stream are reported. The turbulent properties include the three fluctuating components of velocity and the local turbulent shear stress. The measurements were carried out for values of nondimensional distance, x/S, between 35 and 95, and at a constant Reynolds number of 20,000 with a turbulence level of approximately 0.4 percent. The behavior of turbulent properties of wall jet was discussed on the basis of the experimental results. Furthermore, it was found that the rate of growth of turbulent flow field was different from that of mean field.
