Abstract

Scaling of the dissipative structure of wall-bounded turbulence is tested at high Reynolds number using highly-resolved experimental data. It is found that when suitable scaling parameters are selected, that the dissipative motions follow inner-scaling, even into the outer-scaled regions of the flow, and that certain large-scale descriptions follow outer-scaling, even in the inner scaled regions of the flow. It was also found that these scalings were the same for both pipe and boundary layer flows following correction for external intermittency. This proves the universality of the analysis presented here and demonstrates absolute necessity of the external intermittency corrections.
