On a puzzle posed by the Kurien-Sreenivasan boundary layer experiment
Victor Yakhot
Abstract
The Kolmogorov inertial range ratio of the mixed- to- longitudinal third-order structure functions of isotropic and homogeneous turbulence is S1,2S3,0=1/3. Recent measurements by Kurien and Sreenivasan (Phys. Rev. E 64, 056302 (2001)), showed that, while the longitudinal structure function was extremely close to Kolmogorov's, the measured ratio was very far: S1,2S3,0≈ 0.43. Explanation of this puzzle is presented in this letter.
