We present high resolution numerical simulations of compressible magnetohydrodynamic (MHD) turbulence. We concentrate on studies of spectra and anisotropy of velocity and density. We describe a technique of separating different magnetohydrodynamic (MHD) modes (slow, fast and Alfven) and apply it to our simulations. For the mildly supersonic case, velocity and density show anisotropy. However, f...

Introduction. Magnetohydrodynamic (MHD) instabilities in aluminum reduction cells (see Fig. 1) have been the subject of several studies, since the pioneering work of Urata et al. [1]. The interaction between the electrolysis current in the cell and the background magnetic field due to remote currents gives rise to a strong magnetic force acting on the fluids inside the cell. Different kinds of ...

ABSTRACT Astrophysical objects possessing a material surface (white dwarfs, young stars, etc.) may accrete gas from the disc through so-called boundary layer (BL), in which angular velocity of accreting experiences sharp drop. Acoustic waves excited by supersonic shear BL play an important role mediating momentum and mass transport that region. Here we examine characteristics produced different...

In this paper, we describe a general theory of local preconditioning which assigns a unique preconditioner for any set of two-dimensional hyperbolic partial differential equations. The preconditioner is optimal in the sense that it gives the lowest possible condition number (the ratio of maximum to minimum wave speeds). Taking the two-dimensional magnetohydrodynamic (MHD) equations as an exampl...
