Nonexistence 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.

Inviscid Compressible Flow in Meridional Plane of an Axial Flow Compressor

In this paper it is attempted to investigate the behavior of an inviscid flow in the meridional plane of an axial flow compressor. For this purpose the 3-D unsteady Euler equations in cylindrical coordinate are averaged in tangential direction. Therefore, the equations are reduced to a 2-D system. By averaging the tangential component of momentum equation, a blade force will result. Axial and r...

a 2d numerical depth-averaged model for unsteady flow in open channel bends

the purpose of this paper is to present a 2d depth-averaged model for simulating and examining unsteady flow patterns in open channel bends. in particular, this paper proposes a 2d depth-averaged model that takes into account the influence of the secondary flow phenomenon through calculation of the dispersion stresses. the dispersion terms which arose from the integration of the product of the ...

Control of mixing by boundary feedback in 2D channel flow

We address the problem of enhancing mixing by means of boundary feedback control in 2D channel *ow. This is done by 6rst designing feedback control strategies for the stabilization of the parabolic equilibrium *ow, then applying this feedback with the sign of the input reversed. The result is enhanced instability of the parabolic equilibrium *ow, which leads rapidly to highly complex *ow patter...
