Modulational instability (MI), a feature of the nonlinear Schrödinger wave equation, is characterized (to first order) by an exponential growth of sideband components and the formation of distinct wave pulses, often containing extreme waves. Linear stability analysis of the CNLSE shows the effect of crossing angle, q, on MI, and reveals instabilities between 0◦ < q < 35◦, 46◦ < q < 143◦, and 145◦ < q < 180◦. Herein, the modulational stability of crossing wavetrains seeded with symmetrical sidebands is determined experimentally from tests in a circular wave basin. Experiments were carried out at 12 crossing angles between 0◦ ≤ q ≤ 88◦, and strong unidirectional sideband growth was observed. This growth reduced significantly at angles beyond q ≈ 20◦, reaching complete stability at q = 30–40◦. We find satisfactory agreement between numerical predictions (using a time-marching CNLSE solver) and experimental measurements for all crossing angles.

Lvov and Sergey Nazarenko 1Mathematics Institute, The University of Warwick, Coventry, CV4-7AL, UK 2Department of Mathematical Sciences, Rensselaer Polytechnic Institute, Troy, NY 12180 Abstract In this paper we review recent developments in the statistical theory of weakly nonlinear dispersive waves, the subject known as Wave Turbulence (WT). We revise WT theory using a generalisation of the random phase approximation (RPA). This generalisation takes into account that not only the phases but also the amplitudes of the wave Fourier modes are random quantities and it is called the “Random Phase and Amplitude” approach. This approach allows to systematically derive the kinetic equation for the energy spectrum from the the Peierls- Brout-Prigogine (PBP) equation for the multi-mode probability density function (PDF). The PBP equation was originally derived for the three-wave systems and in the present paper we derive a similar equation for the four-wave case. Equation for the multi-mode PDF will be used to validate the statistical assumptions Correspondence/Reprint request: Dr. Sergey Nazarenko, Mathematics Institute, The University of Warwick, Coventry, CV4-7AL, UK E-mail: [email protected] 2 Yeontaek Choi et al. about the phase and the amplitude randomness used for WT closures. Further, the multi- mode PDF contains a detailed statistical information, beyond spectra, and it finally allows to study non-Gaussianity and intermittency in WT, as it will be described in the present paper.

    NOVEMBER 2019 S C H L U T O W 3327 Modulational Stability of Nonlinear Saturated Gravity Waves MARK SCHLUTOW Institut fur€ Mathematik, Freie Universitat€ Berlin, Berlin, Germany (Manuscript received 15 March 2019, in final form 13 July 2019) ABSTRACT Stationary gravity waves, such as mountain lee waves, are effectively described by Grimshaw’s dissipative modulation equations even in high altitudes where they become nonlinear due to their large amplitudes. In this theoretical study, a wave-Reynolds number is introduced to characterize general solutions to these modulation equations. This nondimensional number relates the vertical linear group velocity with wave- number, pressure scale height, and kinematic molecular/eddy viscosity. It is demonstrated by analytic and numerical methods that Lindzen-type waves in the saturation region, that is, where the wave-Reynolds number is of order unity, destabilize by transient perturbations. It is proposed that this mechanism may be a generator for secondary waves due to direct wave–mean-flow interaction. By assumption, the primary waves are exactly such that altitudinal amplitude growth and viscous damping are balanced and by that the am- plitude is maximized. Implications of these results on the relation between mean-flow acceleration and wave breaking heights are discussed. 1.

We extend it in two ways: firstly, we derive a generalized Alber system starting from a system of nonlinear Schrödinger equations, which contains the classical Alber equation as a special case but can also describe crossing seas, i.e., two wavesystems with different wavenumbers crossing. (These can be two completely independent wavenumbers, i.e., in general different directions and different moduli.) We also derive the associated two-dimensional scalar instability condition. This is the first time that a modulation instability condition applicable to crossing seas has been systematically derived for general spectra. Secondly, we use the classical Alber equation and its associated instability condition to quantify how close a given nonparametric spectrum is to being modulationally unstable. We apply this to a dataset of 100 nonparametric spectra provided by the Norwegian Meteorological Institute and find that the Citation: Athanassoulis, A.G.; vast majority of realistic spectra turn out to be stable, but three extreme sea states are found to be Gramstad, O.

  • Wave Turbulence and Intermittency Alan C
    Physica D 152–153 (2001) 520–550 Wave turbulence and intermittency Alan C. Newell∗,1, Sergey Nazarenko, Laura Biven Department of Mathematics, University of Warwick, Coventry CV4 71L, UK Abstract In the early 1960s, it was established that the stochastic initial value problem for weakly coupled wave systems has a natural asymptotic closure induced by the dispersive properties of the waves and the large separation of linear and nonlinear time scales. One is thereby led to kinetic equations for the redistribution of spectral densities via three- and four-wave resonances together with a nonlinear renormalization of the frequency. The kinetic equations have equilibrium solutions which are much richer than the familiar thermodynamic, Fermi–Dirac or Bose–Einstein spectra and admit in addition finite flux (Kolmogorov–Zakharov) solutions which describe the transfer of conserved densities (e.g. energy) between sources and sinks. There is much one can learn from the kinetic equations about the behavior of particular systems of interest including insights in connection with the phenomenon of intermittency. What we would like to convince you is that what we call weak or wave turbulence is every bit as rich as the macho turbulence of 3D hydrodynamics at high Reynolds numbers and, moreover, is analytically more tractable. It is an excellent paradigm for the study of many-body Hamiltonian systems which are driven far from equilibrium by the presence of external forcing and damping. In almost all cases, it contains within its solutions behavior which invalidates the premises on which the theory is based in some spectral range. We give some new results concerning the dynamic breakdown of the weak turbulence description and discuss the fully nonlinear and intermittent behavior which follows.

Academic Editor: Christophe Finot Received: 25 April 2017; Accepted: 13 June 2017; Published: 22 June 2017 Abstract: We investigate modulational instability (MI) in asymmetric dual-core nonlinear directional couplers incorporating the effects of the differences in effective mode areas and group velocity dispersions, as well as phase- and group-velocity mismatches. Using coupled-mode equations for this system, we identify MI conditions from the linearization with respect to small perturbations. First, we compare the MI spectra of the asymmetric system and its symmetric counterpart in the case of the anomalous group-velocity dispersion (GVD). In particular, it is demonstrated that the increase of the inter-core linear-coupling coefficient leads to a reduction of the MI gain spectrum in the asymmetric coupler. The analysis is extended for the asymmetric system in the normal-GVD regime, where the coupling induces and controls the MI, as well as for the system with opposite GVD signs in the two cores.

  • Laminated Wave Turbulence: Generic Algorithms
    LAMINATED WAVE TURBULENCE: GENERIC ALGORITHMS III Elena Kartashova(1), Alexey Kartashov(2) (1)RISC, J. Kepler University, Linz, Austria (2)AK-Soft, Linz, Austria e-mails: [email protected], [email protected] Abstract Model of laminated wave turbulence allows to study statistical and discrete layers of turbulence in the frame of the same model. Statistical layer is described by Zakharov-Kolmogorov energy spectra in the case of irrational enough dispersion function. Discrete layer is covered by some system(s) of Diophantine equations while their form is determined by wave dispersion function. This presents a very special computational challenge - to solve Diophantine equations in many variables, usually 6 to 8, in high degrees, say 16, in integers of order 1016 and more. Generic algorithms for solving this problem in the case of irrational dispersion function have been presented in our previous papers. In this paper we present a new algorithm for the case of rational dispersion functions. Special importance of this case is due to the fact that in wave systems with rational dispersion the statistical layer does not exist and the general energy transport is governed by the discrete layer alone. arXiv:math-ph/0701030v1 11 Jan 2007 PACS: 47.27.E-, 67.40.Vs, 67.57.Fg Key Words: Laminated wave turbulence, discrete wave systems, computations in integers, algebraic numbers, complexity of algorithm 1 1 Introduction The general theory of fluid mechanics begins in 1741 with the work of Leon- hard Euler who was invited by Frederick the Great to construct an intrinsic system of water fountains.

Waves and their modulations Sylvie Benzoni-Gavage June 26, 2020 Abstract The words of the title, waves and modulations, are ubiquitous in science and tech- nology. They are in particular the purpose of an active field of research in applied mathematics. Modulation 'theory' is fifty years old and nevertheless conceals many open questions. An overview of it is given along a journey in the landscape of a few famous equations in mathematical physics. 1 Oscillations Our life is bound to many periodic phenomena, starting with the rhythm of our heart beat to the rotation on itself and the orbiting of the Earth around the Sun. Mathematically speaking, periodic signals may have all sorts of form but the most basic ones are represented by (co)sine functions. For instance, one may consider an oscillating signal represented as a function of time t by y = cos(!0t), where !0 is a parameter determining how often the signal goes back to its original value.
