Descriptions
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, the local turbulent shear stress. The measurements were carried out for values of non-dimensional distance, x/S, between 35 and 95,and at a constant Reynolds number U_0S/υ=2×(10)^4 with a turbulence level of approximately 0.4 percent. The behaviour of turbulent properties of wall jet was discussed in some detail 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.
