up to (r-r„)/6 = 0.6, and that the value of a, decreased toward the edge 



of the boundary layer. The values of a, measured on the present axisym- 



metric body are shown in Figure 10. The present results are similar to the 



earlier results of Huang et al. The values of a, decrease in the inner 



region at the location of x/L = 0.987. 



No attempt was made to remove the free-stream turbulence fluctuations 



from the measured components of turbulence velocities. The reduction in 



the value of a near the edge of the boundary layer is in part caused by

the larger contribution of the free-stream turbulence to q" than to -u'v'
