Journal ArticleDOI
Simultaneous skin friction and velocity measurements in high Reynolds number pipe and boundary layer flows
R. Baidya,Woutijn J. Baars,Spencer Zimmerman,Milad Samie,R. J. Hearst,Eda Dogan,Lucia Mascotelli,Xiaobo Zheng,Gabriele Bellani,Alessandro Talamelli,Bharathram Ganapathisubramani,Nicholas Hutchins,Ivan Marusic,Joseph Klewicki,Jason Monty +14 more
TL;DR: In this paper, a correlation analysis on a per-scale basis between the velocity and reference skin friction signals is performed to reveal which velocity-based turbulent motions are stochastically coherent with turbulent skin friction.
Journal ArticleDOI
Characterization of very-large-scale motions in high-Re pipe flows

TL;DR: In this article, very large-scale structures in pipe flows are characterized using an extended Proper Orthogonal Decomposition (POD)-based estimation, where synchronized non-time-resolved Particle Image Velocimetry (PIV) and multi-point hotwire measurements are integrated for the estimation of turbulent structures in a pipe flow at friction Reynolds numbers of 9500 and 20000.
Journal ArticleDOI
A comparative study of the velocity and vorticity structure in pipes and boundary layers at friction Reynolds numbers up to 10(4)
Spencer Zimmerman,Jimmy Philip,Jason Monty,Alessandro Talamelli,Ivan Marusic,B. Ganapathisubramani,R. J. Hearst,Gabriele Bellani,R. Baidya,Milad Samie,Xiaobo Zheng,Eda Dogan,Lucia Mascotelli,Joseph Klewicki +13 more
TL;DR: In this article, Kwon et al. measured the full velocity and vorticity vectors in both pipe and boundary layer flows under matched spatial resolution and Reynolds number conditions, and found significant differences in the two transverse Reynolds normal stresses throughout the log layer and wake layer at Reynolds numbers.

TL;DR: In this article, correlation-based analysis is used to extract features of inter-scale modulation in turbulent pipe flows, and the R e τ -independence of geometric features is shown with the outer scaling.
