Examining The Inertial Subrange With Nanoscale Cross-Wire Measurements Of Turbulent Pipe Flow At High Reynolds Number Near The Centreline [Post-Print], Clayton P. Byers, Marcus Hultmark, Ivan Marusic, Matt K. Fu

Faculty Scholarship

Highly resolved, two-component velocity measurements were made near the centreline of turbulent pipe flow for Reynolds numbers in the range . These unique data were obtained with a nanoscale cross-wire probe and used to examine the inertial subrange scaling of the longitudinal and transverse velocity components. Classical dissipation rate estimates were made using both the integration of one-dimensional dissipation spectra for each velocity component and the third-order moment of the longitudinal structure function. Although the second-order moments and one-dimensional spectra for each component showed behaviour consistent with local isotropy, clear inertial range similarity and behaviour were not exhibited in the …
