In the formulation of compressible magnetohydrodynamies (MHD) (i.e., magneto-gas dynamics), a "generalized Ohm's law" is required. In particular, an electron pressure term and a "Hall effect" term may appear as non-negligible additions to the Ohm's law that is conventionally used for...

In this work we numerically test a model of Hall magnetohydrodynamics in the presence of a strong mean magnetic field: the reduced Hall magnetohydrodynamic model (RHMHD) derived by [Gomez et al., Phys. Plasmas 15, 102303 (2008)] with the addition of weak compressible effects. The main advantage...

Numerical studies of the effect of a dc magnetic field on dynamo action (development of magnetic fields with large spatial scales), due to helically-driven magnetohydrodynamic turbulence, are reported. The apparent effect of the dc magnetic field is to suppress the dynamo action, above a...

Fully three-dimensional magnetohydrodynamic (MHD) turbulence at large kinetic and low magnetic Reynolds numbers is considered in the presence of a strong uniform magnetic field. It is shown by numerical simulation of a model of MHD that the energy inverse cascades to longer length scales when...

Direct numerical simulations of two-dimensional magnetohydrodynamic (MHD) flows propagating in a mean uniform magnetic field, with correlated velocity and magnetic fields are discussed. A high correlation inhibits the amount of excitation transferred to small scales, showing steeper spectral...

Magnetohydrodynamic turbulent channel flows under a uniform magnetic field are studied by using a large eddy simulation technique. The effect of a uniform magnetic field is incorporated into the subgrid-scale model in the form of a local damping factor. Compared with the experiment, this model...

Statistical properties of MHD turbulence and the mechanism of turbulent dynamo are investigated by direct numerical simulations of three-dimensional MHD equations. It is assumed that the turbulent field has a high symmetry and that the fluid has hyperviscosity and hypermagnetic diffusivity. An...
