Exact Coherent States
In the (quick) overview of the SSP model, we discussed how the shearing of x-dependent modes by the mean shear leads to a positive feedback on the mean flow. In the SSP model these are the W 2 term in the M equation and the −MW term in the W equation. Although this interaction is not necessary for the self-sustaining process itself, it is the key effect that leads to the R−1 scaling of the tran...
متن کاملNonexistence of Coherent Structures in Two-Dimensional Inviscid Channel Flow
Two-dimensional inviscid channel flow of an incompressible fluid is considered. It is shown that if the flow is steady and features no horizontal stagnation, then the flow must necessarily be a parallel shear flow.
متن کاملThree-Dimensional Simulation of Qeshm Channel Currents
Qeshm Channel is a shallow and narrow waterway located between Qeshm Island and the mainland in the vicinity of Hormuzgan Province, Islamic Republic of Iran. This channel is important because of its economic, industrial, fisheries and navigation role it plays as well as environmental issues it presents in the region. A prognostic study was performed to simulate currents in this channel, using C...
متن کاملHeat Transfer in Three-Dimensional Flow along a Porous Plate
An analysis of heat transfer in the flow of a viscous, in-compressible fluid along an infinite porous plate is presented when the plate is subjected to a transverse sinusoidal suction. The flow field becomes three-dimensional due to this type of suction velocity. Expressions for the flow and temperature fields are obtained by series expansion method. It is found during the course of discussion ...
متن کاملExtraction of coherent structures in a rotating turbulent flow experiment.
The discrete wavelet transform (DWT) and discrete wavelet packet transform (DWPT) are used to extract and study the dynamics of coherent structures in a turbulent rotating fluid. Three-dimensional turbulence is generated by strong pumping through tubes at the bottom of a rotating tank (48.4 cm high, 39.4 cm diameter). This flow evolves toward two-dimensional (2D) turbulence with increasing heig...
