Abstract
The Reynolds number dependence of measured (and corrected) second-order longitudinal and transverse velocity structure functions is examined by fitting an expression that extends from the smallest dissipative scales to inertial range scales. Results obtained from fitting to data for decaying grid turbulence and on the centerline of turbulent jets indicate an increase, with respect to the Reynolds number, of both longitudinal and transverse scaling exponents. The results should provide a relatively reliable description for the Reynolds number evolution of Kolmogorov-normalized second-order structure functions from viscous to inertial range scales.
