Simultaneous 3D measurement of the translation and rotation of finite size particles and the flow field in a fully developed turbulent water flow
Inertial particles fully developed turbulence Lagrangian Particle Tracking
2012/5/31
We report a novel experimental technique that measures simultaneously in three dimensions the trajectories, the translation, and the rotation of finite size inertial particles together with the turbul...
Superstatistics as the statistics of quasi-equilibrium states: Application to fully developed turbulence
Superstatistics quasi-equilibrium states developed turbulence
2011/8/18
Abstract: In non-equilibrium states, currents are produced by irreversible processes that take a system toward the equilibrium state, where the current vanishes. We demonstrate, in a general setting, ...
Conditional Eulerian and Lagrangian velocity increment statistics of fully developed turbulent flow
Lagrangian velocity increment statistics fully developed turbulent flow
2010/11/16
Conditional statistics of homogeneous isotropic turbulent flow is investigated by means of high-Reynolds number direct numerical simulations performed with $2048^3$ collocation points. Eulerian as we...
Chaotic properties of a fully developed model turbulence
Chaotic properties fully developed model turbulence
2009/11/3
Shell models of turbulence have been employed as toy models which, in their chaotic states, show statistical properties similar to real fluid turbulence, including Kolmogorov energy spectrum and inter...
Analysis of phase coherence in fully developed atmospheric turbulence:Amazon forest canopy
phase coherence fully developed atmospheric turbulence Amazon forest canopy
2009/11/2
In a recent paper (Koga et al., 2007) it was shown that the intermittent nature of solar wind turbulence can be characterized by kurtosis and phase coherence index. In this paper, we apply these two n...
LAMINAR FULLY DEVELOPED MIXED CONVECTION WITH VISCOUS DISSIPATION IN A UNIFORMLY HEATED VERTICAL DOUBLE-PASSAGE CHANNEL
convection channel double-passage
2009/10/14
Fully developed laminar mixed convection has been investigated numerically in a vertical double-passage channel by taking into account the effect of viscous dissipation. The channel is divided into tw...
A Numerical Study on Fully Developed Fluid Flow and Heat Transfer in a Spiral Finned Tube
fluid flow and heat transfer numerical simulation finned tube
2009/4/28
In this paper, the standard k-ε two-equation model is adopted to numerically simulate fully developed fluid flow and heat transfer in a spiral finned tube within a cracking furnace for ethylene manu...
Fractal derivative multi-scale model of fluid particle transverse accelerations in fully developed turbulence
fully developed homogeneous turbulence probability density function (PDF) anomalous diffusion power-stretched Gaussian distribution
2010/10/22
The Tsallis distribution and the stretched exponential distribution were successfully used to fit the experimental data of turbulence particle acceleration published in Nature (2001), which manifested...
On the Existence of a Fully Developed Wind-Sea Spectrum
Wind-Sea Spectrum wave-wave interaction equilibrium solution
2009/1/20
We consider the energy transfer equation for well-developed ocean waves under the influence of wind, and study the conditions for the existence of an equilibrium solution in which wind input, wave-wav...
An Observation of the Directional Wave Spectrum Evolution from Shoreline to Fully Developed
Surface Contour Radar Directional Wave Spectrum Evolution Fully Developed
2008/12/30
The Surface Contour Radar (SCR) is a 36-GHz computer-controlled airborne system, which produces ocean directional wave spectra with much higher angular resolution than pitch-and-roll buoys. SCR observ...
Eddy Amplitudes and Fluxes in a Homogeneous Model of Fully Developed Baroclinic Instability
Eddy Amplitudes Baroclinic Instability Homogeneous Model
2008/12/12
A horizontally homogeneous two-layer quasigeostrophic model with imposed environmental vertical shear is used to study eddy energies and fluxes in the regime in which an inverse barotropic energy casc...
Recent tests of all generations of numerical wave models indicate that extreme wave heights are significantly underpredicted by these models. This behavior is consistent with the finding by Ewing and ...
