Further support for Townsend’s Reynolds number similarity hypothesis in high Reynolds number rough-wall pipe flow

Measurements of turbulence behavior in high Reynolds number fully developed rough-wall pipe flow are presented. The data are acquired with single-component conventional hot-wire anemometry in the Princeton/ONR Superpipe fitted with a honed rough pipe. Streamwise turbulence intensities, higher-order...

Summary:Measurements of turbulence behavior in high Reynolds number fully developed rough-wall pipe flow are presented. The data are acquired with single-component conventional hot-wire anemometry in the Princeton/ONR Superpipe fitted with a honed rough pipe. Streamwise turbulence intensities, higher-order moments, and spectra are compared with the corresponding results from a previous smooth-wall pipe flow study in the same facility. Accepting the experimental challenges of conducting hot-wire anemometry studies in such a facility, the rough-wall data agree well with the smooth-wall data in the outer region of the flow, strongly supporting Townsend’s Reynolds number similarity hypothesis.
