Hierarchical structures in a turbulent pipe flow
Fluid Dynamics Research, 2003Summary: A hierarchical structure (HS) analysis (\(\beta\)-test and \(\gamma\)-test) is applied to a fully developed turbulent pipe flow. Velocity signals are measured at two cross-sections in the pipe and at a series of radial locations from the pipe wall.

Condensation of Coherent Structures in Turbulent Flows
Physical Review Letters, 2015Coherent structures are ubiquitous in turbulent flows and play a key role in transport. The most important coherent structures in thermal turbulence are plumes. Despite being the primary heat carriers, the potential of manipulating thermal plumes to transport more heat has been overlooked so far.

Structure Functions In A Wall-Turbulent Shear Flow
Boundary-Layer Meteorology, 2002Wavelet and quadrant analyses were applied to turbulent velocity data in order to investigate the transition from the anisotropy of energy- containing eddies to the isotropy of the inertial subrange scales. The quadrant analysis of the wavelet coefficients of longitudinal and vertical velocity components allows the evaluation of the velocity structure ...

Structure of turbulent pipe flow
Fluid Dynamics, 1968The problem of turbulent flow in a straight circular pipe is solved. We consider a system consisting of the equation of motion, the equation for the turbulence energy, the expression relating the turbulence coefficient with the turbulence scale, and the integral formula for determining the turbulence scale.

Turbulent Structures in Canopy Flows
2014A wind-tunnel experiment has been performed by means of a new forest canopy model. Hot-wire anemometry and Particle Image Velocimetry have been used to describe the flow from the statistical point of view together with a conditional sampling approach based on the Variable Interval Time Average method.

The Structure of Turbulent Flows
2019Structural properties of turbulent flows are introduced and classified in the present chapter. They have been the subject of experimental and theoretical research for a long time, see the proceedings of the IUTAM symposium in Cambridge U.K. 1989 [1] for the topological and geometric aspects of flow structures.
