Turbulence Intensity Scaling: A Fugue
We study streamwise turbulence intensity definitions using smooth- and rough-wall pipe flow measurements made in the Princeton Superpipe. Scaling of turbulence intensity with the bulk (and friction) Reynolds number is provided for the definitions.

Automatic Quantification of Atmospheric Turbulence Intensity in Space-Time Domain [PDF]
Quantifying atmospheric turbulence intensity is a challenging task, particularly when assessing real-world scenarios. In this paper, we propose a deep learning method for quantifying atmospheric turbulence intensity based on the space-time domain ...

Turbulence Intensity and the Friction Factor for Smooth- and Rough-Wall Pipe Flow
Turbulence intensity profiles are compared for smooth- and rough-wall pipe flow measurements made in the Princeton Superpipe. The profile development in the transition from hydraulically smooth to fully rough flow displays a propagating sequence from the

Analysis of Dual Polarization Characteristics of Turbulent Structure from Hail Supercell Storms
Convective storms transmit momentum through turbulence, so it is important to understand the echo characteristics of turbulence structure in severe convective storms.Focusing on the velocity spectrum width above 5 m·s -1, the turbulent intensity of two ...

Propagation Properties of an Astigmatic Cos-Gaussian Beam through Turbulent Atmosphere [PDF]
We use the extended Huygens-Fresnel integral to investigate the propagation properties of a cos-Gaussian beam (cosGB) with astigmatism in atmospheric turbulence.

A Spectrum Correction Method Based on Optimizing Turbulence Intensity
Based on the classical spectral representation method of simulating turbulent wind speed fluctuation, a harmonic superposition algorithm was introduced in detail to calculate the homogeneous turbulence wind field simulation in space. From the view of the
