The influence of a mean magnetic field on three-dimensional magnetohydrodynamic turbulence. Journal of Fluid Mechanics., 280, 95-117.https://hdl.handle.net/10289/8620Building on results from two-dimensional magnetohydrodynamic (MHD) turbulence (Shebalin, Matthaeus & Montgomery 1983), the development of anisotropic states from initially isotropic ones is investigated numerically for fully three-dimensional incompressible MHD turbulence. It is found that when an external d.c. magnetic field (B₀) is imposed on viscous and resistive MHD systems, excitations are preferentially transferred to modes with wavevectors perpendicular to B₀). The anisotropy increases with increasing mechanical and magnetic Reynolds numbers, and also with increasing wavenumber. The tendency of B₀ to inhibit development of turbulence is also examined.application/pdfen© 1994 Cambridge University Press.magnetohydrodynamics (MHD)Journal Article10.1017/s0022112094002867
