Two-Front Traveling Waves in Filtration Combustion
SIAM Journal on Applied Mathematics, 1993This paper considers a model of filtration combustion in a porous layer immersed in a bath of gaseous oxidizer at constant pressure \(p_ 0\), which provides for exchange of the oxidizer between the pores, which have initial pressure \(p_ 0\), and the bath.

Traveling Waves Along the Front of a Pulsating Flame
SIAM Journal on Applied Mathematics, 1982A diffusional-thermal model describing the combustion of a premixed gas is considered. We show that a uniformly propagating plane flame is unstable to two-dimensional disturbances when the Lewis number L exceeds a critical value $L_c $. We employ a nonlinear analysis to show that for $L > L_c $ two types of solutions bifurcate from the uniformly ...

Optical Probe Of Standing Wave For Visualization Of Ultrasonic Traveling Wave Front
LEOS '90. Conference Proceedings IEEE Lasers and Electro-Optics Society 1990 Annual Meeting, 1990Optical probe for visualizing ultrasonic traveling wave-front has long attracted considerable attention in the acoustics field. In recent years, we have established a series of methods to display the image of wave-front for ultrasonic traveling wave of an acousto-optic device.

Creeping fronts and travelling waves
Chemie Ingenieur Technik, 1979AbstractSome of the ramifications of Wicke's work on creeping fronts in fixed beds are reviewed in this paper. His work laid the experimental foundations for model building by Vortmeyer and Jahnel on the one hand and by Amundson and Rhee on the other. These workers showed how slowly moving waves could arise in various models of these systems.

Scroll Wave Filaments Terminate in the Back of Traveling Fronts
The Journal of Physical Chemistry A, 2007Experiments with the 1,4-cyclohexanedione Belousov-Zhabotinsky reaction demonstrate that three-dimensional scroll waves can rotate around filaments that end in the wake of a traveling excitation pulse. The vortex structures nucleate during the collision of three nonrotating excitation pulses. The nucleation process and the wave-termination of filaments

Neutrally stable fronts of slow convective traveling waves
Physical Review A, 1990I report experiments on a new confined state of convection, in which slow traveling rolls exist in a region of arbitrary length in a rectangular cell, separated from the rest by a front that can be motionless. In contrast to other ``confined'' states observed in this system, the convective state behind this front is well understood on the basis of the ...

The evolution of travelling wave-fronts in a hyperbolic Fisher model. I. The travelling wave theory
IMA Journal of Applied Mathematics, 2007In this paper, we consider an initial-value problem for a hyperbolic Fisher equation. In particular, we consider the corresponding travelling wave problem and establish the conditions under which permanent-form travelling wave solutions exist. Numerical simulations of the initial-value problem are also presented.

Traveling wave fronts in a delayed lattice competitive system
Applicable Analysis, 2017This paper is concerned with the existence, asymptotic behavior, strict monotonicity, and uniqueness of traveling wave fronts connecting two half-positive equilibria in a delayed lattice competitive system. We first prove the existence of traveling wave fronts by constructing upper and lower solutions and Schauder’s fixed point theorem, and then, for ...
