Computation of Kolmogorov’s Constant in Magnetohydrodynamic Turbulence
نویسندگان
چکیده
In this paper we calculate Kolmogorov’s constant for magnetohydrodynamic turbulence to one loop order in perturbation theory using the direct interaction approximation technique of Kraichnan. We have computed the constants for various Eu(k)/Eb(k), i.e., fluid to magnetic energy ratios when the normalized cross helicity is zero. We find that K increases from 1.47 to 4.12 as we go from fully fluid case (Eb = 0) to a situation when Eu/Eb = 0.5, then it decreases to 3.55 in a fully magnetic limit (Eu = 0). When Eu/Eb = 1, we find that K = 3.43. PACS number: 47.65.+a, 47.25.cg, 52.35

RG Analysis of the Kolmogorov Cascade in Isotropic Turbulence
We review the application of renormalization group (RG) methods to the problem of isotropic turbulence, with attention to Kolmogorov’s phenomenological scaling law. We see that RG reproduces the form of the 5/3 law and can also be used to obtain estimates of the Kolmogorov constant that agree with experiment and numerical simulation. The articles reviewed also confirm the universality of the sc...
متن کاملField theoretic calculation of renormalized viscosity, renormalized resistivity, and energy fluxes of magnetohydrodynamic turbulence.
A self-consistent renormalization scheme has been applied to nonhelical magnetohydrodynamic (MHD) turbulence with zero cross helicity. Kolmogorov's 5/3 power law has been shown to be a consistent solution for d> or =d(c) approximately 2.2. For Kolmogorov's solution, both renormalized viscosity and resistivity are positive for the whole range of parameters. Various cascade rates and Kolmogorov's...
متن کاملLinear coupling and over-reflection phenomena of magnetohydrodynamic waves in smooth shear flows
Abstract Special features of magnetohydrodynamic waves linear dynamics in smooth shear flows are studied. Quantitative asymptotic and numerical analysis are performed for wide range of system parameters when basic flow has constant shear of velocity and uniform magnetic field is parallel to the basic flow. The special features consist of magnetohydrodynamic wave mutual transformation and over-r...
متن کاملKolmogorov’s law for two-dimensional electron-magnetohydrodynamic turbulence
The analogue of the Kolmogorov’s four-fifths law is derived for twodimensional, homogeneous, isotropic EMHD turbulence in the energy cascade inertial range. Direct numerical simulations for the freely decaying case show that this relation holds true for different values of the adimensional electron inertial length scale, de. The energy spectrum is found to be close to the expected Kolmogorov sp...
متن کاملSolutions of Conformal Turbulence on a Half Plane
Exact solutions of conformal turbulence restricted on a upper half plane are obtained. We show that the inertial range of homogeneous and isotropic turbulence with constant enstrophy flux develops in a distant region from the boundary. Thus in the presence of an anisotropic boundary, these exact solutions of turbulence generalize Kolmogorov’s solution consistently and differ from the Polyakov’s...
