Stochastic Three-Dimensional Rotating Navier–Stokes Equations: Averaging, Convergence and Regularity
We consider stochastic three-dimensional rotating Navier?CStokes equations and prove averaging theorems for stochastic problems in the case of strong rotation. Regularity results are established by bootstrapping from global regularity of the limit stochastic equations and convergence theorems. 相似文献

Families of N interacting curves are considered, with long range, mean field type, interaction. They generalize models based on classical interacting point particles to models based on curves. In this new set-up, a mean field result is proven, as \(N\rightarrow \infty \). The limit PDE is vector valued and, in the limit, each curve interacts with a mean field solution of the PDE. This target is reached by a careful formulation of curves and weak solutions of the PDE which makes use of 1-currents and their topologies. The main results are based on the analysis of a nonlinear Lagrangian-type flow equation. Most of the results are deterministic; as a by-product, when the initial conditions are given by families of independent random curves, we prove a propagation of chaos result. The results are local in time for general interaction kernel, global in time under some additional restriction. Our main motivation is the approximation of 3D-inviscid flow dynamics by the interacting dynamics of a large number of vortex filaments, as observed in certain turbulent fluids; in this respect, the present paper is restricted to smoothed interaction kernels, instead of the true Biot–Savart kernel. 相似文献

The strong existence and the pathwise uniqueness of solutions with \({L^{\infty}}\)-vorticity of the 2D stochastic Euler equations are proved. The noise is multiplicative and it involves the first derivatives. A Lagrangian approach is implemented, where a stochastic flow solving a nonlinear flow equation is constructed. The stability under regularizations is also proved. 相似文献

A stochastic infinite dimensional version of the GOY model is rigorously investigated. Well posedness of strong solutions, existence and p-integrability of invariant measures is proved. Existence of solutions to the zero viscosity equation is also proved. With these preliminary results, the asymptotic exponents ζp of the structure function are investigated. Necessary and sufficient conditions for ζ2≥ 2/3 and ζ2=2/3 are given and discussed on the basis of numerical simulations. 相似文献

Rigorous Remarks about Scaling Laws in Turbulent Fluids 总被引:1,自引:0,他引:1

A definition of scaling law for suitable families of measures is given and investigated. First, a number of necessary conditions
are proved. They imply the absence of scaling laws for 2D stochastic Navier-Stokes equations and for the stochastic Stokes
(linear) problem in any dimension, while they imply a lower bound on the mean vortex stretching in 3D. Second, for the 3D
stochastic Navier-Stokes equations, necessary and sufficient conditions for scaling laws to hold are given, translating the
problem into bounds for energy and enstrophy of high and low modes respectively. Unlike in the 2D case, the validity or invalidity
of such conditions in 3D remains open. 相似文献

3D stochastic Navier-Stokes equations with a suitable nondegenerate noise are considered. Following a method introduced by
Da Prato and Debussche, it is proved that every Markov process associated to the equations has a Strong Feller like continuity
property with respect to initial conditions.

We consider the linear transport equation with a globally Hölder continuous and bounded vector field, with an integrability condition on the divergence. While uniqueness may fail for the deterministic PDE, we prove that a multiplicative stochastic perturbation of Brownian type is enough to render the equation well-posed. This seems to be the first explicit example of a PDE of fluid dynamics that becomes well-posed under the influence of a (multiplicative) noise. The key tool is a differentiable stochastic flow constructed and analyzed by means of a special transformation of the drift of Itô-Tanaka type. 相似文献

By using Malliavin calculus and multiple Wiener-Itô integrals, we study the existence and the regularity of stochastic currents defined as Skorohod (divergence) integrals with respect to the Brownian motion and to the fractional Brownian motion. We consider also the multidimensional multiparameter case and we compare the regularity of the current as a distribution in negative Sobolev spaces with its regularity in the Watanabe spaces. 相似文献
