The turbulent cascade in five dimensionsTo the naked eye, turbulent flows exhibit whirls of many different sizes. To each size, or scale, corresponds a fraction of the total energy resulting from a cascade in five dimensions: scale, tim ...To the naked eyeor scaletim...
We present an experiment where a stretched vortex is experiencing quasiperiodical turbulent bursts inside a laminar environment. The flow is characterized in the spectral and spatial domain using hot film and Particle Image Velocimetry Measurements. Some comparisons with the Lundgren vortex energy cascade...
This paper presents calculations of the Castaing (Physica D, 46, 177, 1990) cascade kernels for five well-known models of the turbulent cascade and demonstrates that these kernels provide conceptually simple and direct descriptions of turbulence models equivalent to their multifractal spectra. The pro...
The turbulent cascade and proton heating in the solar wind during solar minimum.doi:10.1063/1.4811009Solar wind measurements at 1 AU during the recent solar minimum and previous studies of solar maximum provide an opportunity to study the effects of the changing solar cycle on in situ heating. ...

We employed four BCs that are commonly used for airfoil simulations: BC-1, BC-2, BC-3, and BC-4, as described in Table1, applied to the velocity vector,UU, pressure,p, turbulent viscosity or eddy viscosity,νt, and viscosity-like variable,ν~at the inlet (I), top (T), bottom (...

Limitation for the energy spectrum analysis for the understanding of the turbulent cascade能谱在解释湍流能量级串中值得注意的一个问题湍流能量级串能谱用简单的例子说明 ,即使在动力学上表现为不存在的能量级串 ,也在能谱上表现出相当充分的能量向高频或者低频传递的现象 .这些过去都是作为能量级串的证据而被...
As has been emphasized in the literature, under the presence of viscoelastic additives the turbulent cascade to the dissipative scale is terminated prematurely, and scales below a certain limit, designated by the elasticity of the micelles interact with the polymer and not with vortices of larger ...
