Energetic Modes in Turbulent Pipe Flow From Resolvent Analysis [PDF]
, 2010 We describe a method to investigate the mode shapes in turbulent pipe flow at a given wavenumber pair that are most responsive to harmonic forcing in the sense that the they correspond to the largest singular value in a Schmidt decomposition of the ...

Further observations on the mean velocity distribution in fully developed pipe flow [PDF]
, 2004 The measurements by Zagarola & Smits (1998) of mean velocity profiles in fully developed turbulent pipe flow are repeated using a smaller Pitot probe to reduce the uncertainties due to velocity gradient corrections.

On the analytic explanation of experiments where turbulence vanishes in pipe flow [PDF]
, 2022 [Abstract]: The present research will provide an analytical explanation to experiments destabilising turbulence in pipe flow reported in Kuehnen et al. (Nat. Phys., vol. 14, 2018, 386–390). Those experiments show four methods by which turbulence vanishes

Reynolds-number Dependence of Streamwise Velocity Fluctuations in Turbulent Pipe Flow [PDF]
, 2002 Statistics of the streamwise velocity component in fully-developed pipe flow are examined for Reynolds numbers in the range 5.5 x 10^4 < Re_D < 5.7 x 10^6.

The KMOS Deep Survey (KDS) - I. Dynamical measurements of typical star-forming galaxies at z ≃ 3.5 [PDF]
, 2017 We present dynamical measurements from the KMOS (K-band Multi-Object Spectrograph) Deep Survey (KDS), which is comprised of 77 typical star-forming galaxies at z $\simeq$ 3.5 in the mass range 9.0 1), with the sample average V$_{C}$/{\sigma}$_{int ...

Where are the Luminous Red Galaxies (LRGs)? Using correlation measurements and lensing to relate LRGs to dark matter haloes [PDF]
, 2012 Nonlinear redshift-space distortions, the Finger-of-God (FoG) effect, can complicate the interpretation of the galaxy power spectrum. Here, we demonstrate the method proposed by Hikage et al. (2012) to use complimentary observations to directly constrain

Obtaining accurate mean velocity measurements in high Reynolds number turbulent boundary layers using Pitot tubes [PDF]
, 2013 This article reports on one component of a larger study on measurement of the zero-pressure-gradient turbulent flat plate boundary layer, in which a detailed investigation was conducted of the suite of corrections required for mean velocity measurements ...
