We formulate a theory for the collective phase description of oscillatory convection in Hele-Shaw cells. It enables us to describe the dynamics of the oscillatory convection by a single degree of freedom which we call the collective phase. The theory can be considered as a phase reduction method for limit-cycle solutions in infinite-dimensional dynamical systems, namely, stable time-periodic solutions to partial differential equations, representing the oscillatory convection. We derive the…

Phase-reduction for synchronization of oscillating flow by perturbation on surrounding structure

Abstract Regulation of fluid flow by deformations of the surrounding elastic structure is observed in many natural and artificial system, such as in the cardiovascular system. As the first step to

Phase-response analysis of synchronization for periodic flows

We apply phase-reduction analysis to examine synchronization properties of periodic fluid flows. The dynamics of unsteady flows is described in terms of the phase dynamics, reducing the

Phase reduction and synchronization of a network of coupled dynamical elements exhibiting collective oscillations.

A general phase reduction method for a network of coupled dynamical elements exhibiting collective oscillations, which is applicable to arbitrary networks of heterogeneous dynamical elements, is

Phase and Amplitude Description of Complex Oscillatory Patterns in Reaction-Diffusion Systems

Spontaneous rhythmic oscillations are widely observed in various real-world systems. In particular, biological rhythms, which typically arise via synchronization of many self-oscillatory cells, often

Phase-based control of periodic flows

This work develops an energy-efficient flow-control strategy to alter the oscillation phase of time-periodic fluid flows rapidly based on the phase-sensitivity function obtained by solving the associated Euler–Lagrange equations as a two-point boundary-value problem.

Phase reduction theory for hybrid nonlinear oscillators.

A general phase reduction theory for weakly perturbed limit cycles in hybrid dynamical systems that facilitates analysis, control, and optimization of nonlinear oscillators whose smooth models are unavailable or intractable is developed.

Synchronization of two coupled turbulent fires.

It is shown that a significant decrease in the distance between the two fire sources gives rise to a synchronized state in the near field dominated by the unstable motion of transverse vortex rings, and the synchronized state vanishes in the far field forming well-developed turbulent plumes.

Adjoint-based phase reduction analysis of incompressible periodic flows

We establish the theoretical framework for adjoint-based phase reduction analysis for incompressible periodic flows. Through this adjoint-based method, we obtain spatiotemporal phase sensitivity fields



Collective phase description of globally coupled excitable elements.

The theory is an extension of the conventional phase reduction method for ordinary limit cycles to limit-cycle solutions in infinite-dimensional dynamical systems, such as the time-periodic solutions to nonlinear Fokker-Planck equations representing macroscopic rhythms.

Synchronization of modulated traveling baroclinic waves in a periodically forced, rotating fluid annulus.

In quasiperiodic and chaotic amplitude-modulated traveling wave regimes, the results demonstrate a strong interaction between the natural periodic modulation of the wave amplitude and the externally imposed forcing, which leads to partial or complete phase synchronization.

Stability and fluctuations of a spatially periodic convective flow

2014 Using a model equation we analyze the onset of convection for a roll instability. The wavelength increase follows from a variational approach. For certain wavelengths, phase diffusion turns out

Dissipative Structures and Weak Turbulence

We present a brief overview of the current understanding of temporal and spatio-temporal chaos, both termed weak turbulence according to the context [1]. The process which allows one to reduce the

A comprehensive review of spatiotemporal pattern formation in systems driven away from equilibrium is presented, with emphasis on comparisons between theory and quantitative experiments. Examples

Synchronized chaos in geophysical fluid dynamics.

Fluid flow fields in a pair of quasi-two-dimensional channel models synchronize if only the small-scale eddy components of the two flows are coupled, implying a relationship between the Atlantic and Pacific sectors of the Earth's climate system.
