Flame Propagation in Poiseuille Flow

39th Aerospace Sciences Meeting and Exhibit, 2001
We describe flame propagation in a channel subject to a Poiseuille flow within the context of a thermo-diffusive model under (i) adiabatic conditions, and (ii) in the presence of conductive heat losses at the walls. The curved two-dimensional lfames examined may be either assisted or opposed by the flow.

Passivity of plane Poiseuille flow

2013 European Control Conference (ECC), 2013
This paper considers the passivity of plane Poiseuille flow, which is the incompressible flow observed between two parallel plates that are assumed to be of infinite extent. A model in which the flow is considered as the feedback connection between a linear time-invariant system and a static, memoryless nonlinear system is used.

Stability of Pipe Poiseuille Flow

The Physics of Fluids, 1968
The stability of pipe Poiseuille flow with respect to linear azimuthally periodic disturbances is investigated. It is found that many radial modes of disturbance exist for each azimuthal periodicity. No linear instability is found for the mode sets with azimuthal periodicity of one.

Interaction of peristaltic motion with Poiseuille flow

Bulletin of Mathematical Biology, 1974
The effect of Poiseuille flow on peristaltic transport has been investigated in a two-dimensional mathematical model of peristalsis for the case when the wall of the channel executes a sinusoidal motion of small amplitude. Closed-form solutions have been obtained for limiting values of Reynolds number and the Poiseuille flow parameter, while the method

The Stability of Plane Poiseuille Flow

Physical Review, 1952
The problem of the stability of plane Poiseuille flow to small disturbances leads to a characteristic value problem for the Orr-Sommerfeld equation with given boundary conditions. It happens that negative values of the imaginary parts of the characteristic numbers, which indicate instability, are small, at any rate over the region here investigated ...

Generation of umbilics by Poiseuille flows

The European Physical Journal E, 2014
The Fredericks transition in homeotropic nematic layers submitted to an electric field can be described in terms of a 2D vectorial order parameter [Formula: see text]. We have shown previously that umbilics which are point defects of the field [Formula: see text] can be generated in a controlled manner by magnetic fields.

Poiseuille flow of a Quincke suspension

Physical Review E, 2014
The controversy of models of dielectric particle suspensions with antisymmetric stress, which predict a nonphysical cusp of the velocity profile in plane Poiseuille flow under the action of the electrical field, is resolved. In the mean-field approximation, the nonlinear kinetic equation is derived for coupled due to the flow translational and ...

Asymptotic approach to hartmann-poiseuille flows

Journal of Computational Physics, 1969
Abstract The steady state flow is considered of a viscous conducting liquid in the inlet region of a straight channel with or without a transverse magnetic field, particularly the rate of approach of the flow to the Hartmann-Poiseuille patterns downstream.

Stability of Poiseuille Flow in Elastic Tubes

Journal of Applied Mechanics, 1977
This paper presents a theoretical analysis of the temporal and spatial stability of Poiseuille flow in elastic tubes to infinitesimal axisymmetric disturbances. A cylindrical shell model which includes the effects of transverse shear and rotatory inertia is employed for the tube wall.
