Roughness-induced critical phenomena in a turbulent flow

Research output: Contribution to journalArticlepeer-review

Abstract

I present empirical evidence that turbulent flows are closely analogous to critical phenomena, from a reanalysis of friction factor measurements in rough pipes. The data collapse found here corresponds to Widom scaling near critical points, and implies that a full understanding of turbulence requires explicit accounting for boundary roughness.
