An analytic model for steady state turbulence is employed to obtain the inertial range power spectrum of compressible turbulence. We assume that for homogeneous turbulence, the timescales controlling the energy injected at a given wavenumber from all smaller wave-numbers, are equal for each spatial component. However, the longitudinal component energy is diverted into compression, so the rate controlling the energy that is transferred to all larger wave-numbers by the turbulent viscosity is… 



The Statistics of Supersonic Isothermal Turbulence

We present results of large-scale three-dimensional simulations of supersonic Euler turbulence with the piecewise parabolic method and multiple grid resolutions up to 20483 points. Our numerical

Analytical model for large-scale turbulence.

An analytical model for large-scale turbulence is presented, based on a new closure which depends on the growth rate of the instability-generating turbulence, which can readily be extended to include magnetic fields and rotation.

Stellar Turbulent Convection: A Self-consistent Model

We present a self-consistent model for stellar turbulent convection that is similar in spirit to the CM model (Canuto & Mazzitelli 1991) since it accounts for the full spectrum of the turbulent

A model for fully developed turbulence

A model for stationary, fully developed turbulence is presented. The physical model used to describe the nonlinear interactions provides an equation for the turbulent spectral energy function F(k) as

Local Structure Of Turbulence in an Incompressible Viscous Fluid at Very Large Reynolds Numbers

§1. We denote by ua(P) = ua(xl, x2, x3, t), a= 1,2,3, the velocity components at time t at a point with rectangular Cartesian coordi­nates xi, x2, x3. When studying turbulence it is natural to regard

A Search for Larson-type Relations in Numerical Simulations of the ISM: Evidence for Nonconstant Column Densities

We present results from a statistical study of clouds in two-dimensional numerical simulations of the interstellar medium. The clouds in the simulations exhibit a differential mass spectrum dN(M)/dM

Spectra from the shocked nebulae revealing turbulence near the Galactic Centre

The spectra emitted from clouds near the Galactic Centre (GC) are investigated calculating the UV-optical-IR lines using the physical parameters and the element abundances obtained by the detailed

Origin and structure of isolated dark globules

High resolution carbon monoxide observations of over a dozen isolated dark globules indicate that a power-law correlation exists between the internal velocity dispersion and cloud size. The power-law

The Power Spectrum and Structure Function of the Gamma-Ray Emission from the Large Magellanic Cloud

The Fermi-LAT observational data of the diffuse γ ray emission from the Large Magellanic Cloud (LMC) were examined to test for the existence of underlying long-range correlations. A statistical test

A power spectrum analysis of the angular scale of Galactic neutral hydrogen emission towards l=140°, b=0°

Angular power spectra are derived from the DRAO Galactic Plane Survey for H I emission with velocities between ≃ 0 and ≃ − 95 km s −1 with respect to the Local Standard of Rest. The angular scales
