چکیده

We present preliminary results from two computational magnetohydrodynamic (MHD) studies of magnetic nozzles. The first study models the magnetic nozzle expansion of a plasma into a near vacuum with a resistive MHD solver. Results from resistive MHD simulations suggest that further model development is necessary to replicate experimental results within the desired physical regime. The second study investigates the flow of a magnetically guided plasma into a background plasma using a generalized Ohm’s law MHD solver. Results from the generalized Ohm’s law MHD simulations of the non-expanding jet are obtained using the Magneto-Gas Kinetic Method. Generalized Ohm’s law simulations show bulk rotation of the plasma jet and the formation of helical structures in the velocity and current due to the Hall effect.

Effects of variations in magnetic Reynolds number on magnetic field distribution in electrically conducting fluid under magnetohydrodynamic natural convection

In this study the effect of magnetic Reynolds number variation on magnetic distribution of natural convection heat transfer in an enclosure is numerically investigated. The geometry is a two dimensional enclosure which the left wall is hot, the right wall is cold and the top and bottom walls are adiabatic. Fluid is molten sodium with Pr=0.01 and natural convection heat transfer for Rayleigh num...

Some First Steps Towards a Radiation GRMHD Code: Radiative Effects on Accretion Rate onto a Kerr Black Hole

The role of radiation in general relativistic magnetohydrodynamic (GRMHD) accretion simulations is discussed through axisymmetric simulations of the evolution of an initial torus seeded with a weak magnetic field. The paper compares and contrasts the rate of accretion onto a Kerr black hole and mass flux out out of the initial torus at large radii in the GRMHD code of De Villiers & Hawley and a...

Long-term memory in experiments and numerical simulations of hydrodynamic and magnetohydrodynamic turbulence.

We analyze time series stemming from experiments and direct numerical simulations of hydrodynamic and magnetohydrodynamic turbulence. Simulations are done in periodic boxes, but with a volumetric forcing chosen to mimic the geometry of the flow in the experiments, the von Kármán swirling flow between two counterrotating impellers. Parameters in the simulations are chosen to (within computationa...

Cosmic Structure Formation and Dynamics: Magnetohydrodynamic Simulations of Coronal Heating

By implementing a three-dimensional magnetohydrodynamic (MHD) code based on the CIP-MOCCT scheme, we carried out large scale MHD simulations of the solar atmosphere covering the region from the convection zone to the corona. We found that in regions with weak magnetic fields (B~100G), horizontal magnetic loops created in the upflow regions of the convection generate high frequency waves by reco...

Magnetohydrodynamic Simulations of Black Hole Accretion

We discuss the results of three-dimensional magnetohydrodynamic simulations, using a pseudo-Newtonian potential, of thin disk (h/r ≈ 0.1) accretion onto black holes. We find (i) that magnetic stresses persist within rms, the marginally stable orbit, and (ii) that the importance of those stresses for the dynamics of the flow depends upon the strength of magnetic fields in the disk outside rms. S...
