Coherence in the turbulent cascade
نویسنده
چکیده
The model assumes that each step generates eddies with smaller length scales ∆x, usually ∆02. After the initial effects are forgotten, the probability distribution of vn is completely determined by the distribution W of the ‘breakdown coefficients’ vn/vn−1 (Frisch, 1995). These assumptions are known to describe well some of the statistical properties of isotropic turbulence and, in particular, the scaling exponents of the velocity structure functions (Meneveau & Sreenivasan, 1991),

Sound-wave coherence in atmospheric turbulence with intrinsic and global intermittency.
The coherence function of sound waves propagating through an intermittently turbulent atmosphere is calculated theoretically. Intermittency mechanisms due to both the turbulent energy cascade (intrinsic intermittency) and spatially uneven production (global intermittency) are modeled using ensembles of quasiwavelets (QWs), which are analogous to turbulent eddies. The intrinsic intermittency is ...
متن کاملNumerical Investigation on Compressible Flow Characteristics in Axial Compressors Using a Multi Block Finite Volume Scheme
An unsteady two-dimensional numerical investigation was performed on the viscous flow passing through a multi-blade cascade. A Cartesian finite-volume approach was employed and it was linked to Van-Leer's and Roe's flux splitting schemes to evaluate inviscid flux terms. To prevent the oscillatory behavior of numerical results and to increase the accuracy, Monotonic Upstream Scheme for Conservat...
متن کاملTurbulence in Thick Layers
Properties of turbulence, such as the direction of the energy cascade depend on the flow dimensionality. Recent experimental results reveal new physics understanding of flows in thick layers. We show that the flow dimensionality can be characterized by the flow damping and that a comparison of the decay rate with that of a quasi-2D flow can be used as a measure of dimensionality of a turbulent ...
متن کاملTrapping, Anomalous Transport, and Quasi-coherent Structures in Magnetically Confined Plasmas∗)
Strong electrostatic turbulence in magnetically confined plasmas is characterized by trapping or eddying of particle trajectories produced by the E × B stochastic drift. Trapping is shown to produce strong effects on test particles and on test modes by causing nonstandard trajectory statistics: non-Gaussian distribution, memory effects, and coherence. Trapped trajectories form quasi-coherent st...
متن کاملInvestigation of Coherent and Incoherent Laser Beams Propagation Through Turbulent Atmosphere
In this paper propagation of combined laser beam through atmosphere is investigated. Laser beam is combined via lens array arrangement. Turbulence is considered as an affecting factor of atmosphere and its effects on transverse coherence length (Fried parameter), peak intensity, propagation efficiency, and spot size of the laser beam is investigated. Coherent and incoherent combined beam are co...
