High resolution simulations of supersonic turbulence in molecular clouds
We present the results of three-dimensional simulations of supersonic Euler turbulence with grid resolutions up to 1024 points. Our numerical experiments describe nonmagnetized driven turbulent flows with an isothermal equation of state and an rms Mach number of 6. We demonstrate that the inertial range scaling properties of turbulence in this strongly compressible regime deviate substantially ...

15 صفحه اولSimulations of Supersonic Turbulence in Molecular Clouds: Evidence for a New Universality
We use three-dimensional simulations to study the statistics of supersonic turbulence in molecular clouds. Our numerical experiments describe driven turbulent flows with an isothermal equation of state, Mach numbers around 10, and various degrees of magnetization. We first support the so-called 1/3-rule of Kritsuk et al. (2007a) with our new data from a larger 2048 simulation. We then attempt t...
متن کاملFractal Density Distribution of Interstellar Clouds from Numerical Simulations of Compressively Driven Supersonic Turbulence
We present results of a high resolution 3-dimensional numerical simulation of compressively driven supersonic turbulence. A detailed analysis of the fractal mass dimension, which is extracted from data of the density field, yields values of Df ≈ 2.6− 2.7. This is significantly higher than what is usually assumed in the literature (Df ≈ 2.35). However, this value is traditionally obtained by app...
متن کاملThe Statistics of Supersonic Isothermal Turbulence
We present results of large-scale three-dimensional simulations of supersonic Euler turbulence with the piecewise parabolic method (PPM) and multiple grid resolutions up to 20483 points. Our numerical experiments describe non-magnetized driven turbulent flows with an isothermal equation of state and an rms Mach number of 6. We discuss numerical resolution issues and demonstrate convergence, in ...
