Report

Rich recirculation patterns have been recently discovered in the electrically conducting flow subject to a local external magnetic termed "the magnetic obstacle" [Phys. Rev. Lett. 98 (2007), 144504]. This paper continues the study of magnetic obstacl

Report

On the analogy between streamlined magnetic and solid obstacles

Autor: Votyakov, E. V., Kassinos, S. C.

Publikováno v: Phys. Fluids 21, 097102 (2009)

Analogies are elaborated in the qualitative description of two systems: the magnetohydrodynamic (MHD) flow moving through a region where an external local magnetic field (magnetic obstacle) is applied, and the ordinary hydrodynamic flow around a soli

Analytic models of heterogenous magnetic fields for liquid metal flow simulations

Autor: Votyakov, E. V., Kassinos, S. C., Albets-Chico, X.

Publikováno v: Theor. Comput. Fluid Dyn. (2009) 23:571\^a?"578

A physically consistent approach is considered for defining an external magnetic field as needed in computational fluid dynamics problems involving magnetohydrodynamics (MHD). The approach results in simple analytical formulae that can be used in num

Thermal Conduction in Magnetized Turbulent Gas

Autor: Cho, J., Lazarian, A., Honein, A., Knaepen, B., Kassinos, S., Moin, P.

Publikováno v: Astrophys.J. 589 (2003) L77-L80

Using numerical methods, we systematically study in the framework of ideal MHD the effect of magnetic fields on heat transfer within a turbulent gas. We measure the rates of passive scalar diffusion within magnetized fluids and make the comparisons a
