Abstract

Measured second- and third-order moments of longitudinal and transverse velocity increments are examined for relatively large values of the Taylor microscale Reynolds number $R_{\lambda}$ in highly turbulent shear flows. The results support an approach to a Kolmogorov-like inertial range only at very large values of $R_{\lambda}$ . Correspondingly, the difference between inertial range power law exponents of longitudinal and transverse velocity structure functions continues to diminish as $R_{\lambda}$ increases.
