Different variants of hybrid kinetic-fluid models are considered for describing the interaction of a bulk fluid plasma obeying magnetohydrodynamics (MHD) and an energetic component obeying a kinetic theory. Upon using the Vlasov kinetic theory for energetic particles, two planar Vlasov-MHD models are compared in terms of their stability properties. This is made possible by the Hamiltonian struc...

Two scientiic application programs, the Versatile Advection Code and the HEating by Resonant Absorption code are adapted to parallel computer platforms. Both programs can solve the time dependent nonlinear partial diierential equations of magnetohydrodynamics with diierent numerical schemes. We describe our approach to parallelize the original Fortran 90 source codes using High Performance Fort...

Three-dimensional hybrid simulations with kinetic ions and fluid electrons of Z-pinch plasmas are being used to investigate the linear and nonlinear development of sausage and kink instabilities with model profiles in the presence of effects which go beyond ideal magnetohydrodynamics. In addition, the hybrid simulations are also being applied to model start-up plasmas in long pulse Z-pinch impl...

Abstract We derive an exact, time-dependent analytical magnetic field solution for the inner heliosheath, which satisfies both induction equation of ideal magnetohydrodynamics in limit infinite electric conductivity and divergence constraint. To this end, we assume that is frozen into a plasma flow resembling characteristic interaction solar wind with local interstellar medium. Furthermore, mak...

Abstract In plasma turbulence, energy and cross helicity are transferred across scales at a constant rate as consequence of nonlinear interactions. incompressible magnetohydrodynamics (MHD), the cascade both quantities can be computed by means temporal evolution second-order structure functions, known Karman–Howarth–Monin (KHM) equations. present work, we derive KHM equation to compute in compr...

(1) Introduction.-The electromagnetodynamics of fluids combines the dynamics of fluids and electromagnetic theory. It has been independently developed in two theories: magnetohydrodynamics and electrohydrodynamics, depending upon the properties of the fluid considered and the prevalence of either magnetic fields or electric fields. The space permitted here forbids us from going into any apprais...

We obtained self-similar solutions of relativistically expanding magnetic loops taking into account the azimuthal magnetic fields. We neglect stellar rotation and assume axisymmetry and a purely radial flow. As the magnetic loops expand, the initial dipole magnetic field is stretched into the radial direction. When the expansion speed approaches the light speed, the displacement current reduces...
