A theory for the streamwise turbulent fluctuations in high Reynolds number pipe flow [PDF]

, 2013
A new theory for the streamwise turbulent fluctuations in fully developed pipe flow is proposed. The theory extends the similarities between the mean flow and the streamwise turbulence fluctuations, as observed in experimental high Reynolds number data ...

Self-similarity of Mean Flow in Pipe Turbulence [PDF]

, 2006
Based on our previous modified log-wake law in turbulent pipe ‡flows, we invent two compound similarity numbers (Y;U), where Y is a combination of the inner variable y+ and outer variable , and U is the pure exect of the wall.

High Reynolds Number Experiments in the Long Pipe at CICLoPE [PDF]

, 2020
In aerospace applications 50% of the drag is due to the friction experienced in the turbulent boundary layer. To reduce drag, it is important to rely on accurate numerical codes to correctly predict friction.

First-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Determination of Cosmological Parameters [PDF]

, 2003
WMAP precision data enable accurate testing of cosmological models. We find that the emerging standard model of cosmology, a flat Λ-dominated universe seeded by a nearly scale-invariant adiabatic Gaussian fluctuations, fits the WMAP data.

Fusion Reaction Measurements in the Princeton Large Tokamak

, 1983
The d(d,n)3 He, d(d,p)t, d(t,n)α, and d(3He,p)α fusion reactions have been measured by detection of the 2.5 MeV neutron, 3 MeV proton, 14 MeV neutron and 14.7 MeV proton emissions, respectively.

Flow in a Commercial Steel Pipe [PDF]

, 2007
Fully-developed turbulent flow in a commercial steel pipe is studied using single component hot-wire probes in both oneand two-point experiments. The streamwise turbulence component was measured over a Reynolds number range from 7.6× 104 to 8.3×106 ...

Turbulent Pipe Flow - High Resolution Measurements in CICLoPE [PDF]

, 2017
The thesis deals with the experimental investigation of turbulent pipe flow at high Reynolds number. Wall-bounded turbulence is an extremely relevant topic for engineering and natural science applications and yet many aspects of the physics are not clear

Assessment of uncertainties in hot-wire anemometry and oil-film interferometry measurements for wall-bounded turbulent flows

, 2018
In this study, the sources of uncertainty of hot-wire anemometry (HWA) and oil-film interferometry (OFI) measurements are assessed. Both statistical and classical methods are used for the forward and inverse problems, so that the contributions to the ...
