Abstract:

A turbulent axisymmetric jet was investigated to determine the axial, radial and tangential components of the fluctuating velocity as well as the axial and radial components of the velocity correlation coefficients at a given point. Also determined were the symmetric and asymmetric correlation coefficients and the transverse turbulence scale. The jet was 150, 440 and 2200 mm in diameter measurements were taken in the initial section submerged jet where the boundary layer is two-dimensional. The results of measurements are shown graphically as families of curves describing the mean velocity, the turbulence intensity, the fluctuating velocity component and various cross plots of these parameters.
