Numerical Simulation of Magnetohydrodynamic Flows
Journal of Spacecraft and Rockets, 2004The development of a versatile computational tool for the solution of turbulent magnetohydrodynamic flows is presented. The flow solver can simulate the full magnetohydrodynamic equations or simplified equations based on the low magnetic Reynolds number approximation. Both laminar and turbulent flows are investigated. The Baldwin‐Lomax turbulence model

Lattice kinetic simulations in three-dimensional magnetohydrodynamics
Physical Review E, 2004A lattice kinetic algorithm to simulate three-dimensional (3D) incompressible magnetohydrodynamics is presented. The fluid is monitored by a distribution function, which obeys a scalar kinetic equation, subject to an external force due to the imposed magnetic field. Following the work of J. Comput. Phys.

Lattice Boltzmann model for simulation of magnetohydrodynamics
Physical Review Letters, 1991A numerical method, based on a discrete Boltzmann equation, is presented for solving the equations of magnetohydrodynamics (MHD). The algorithm provides advantages similar to the cellular automaton method in that it is local and easily adapted to parallel computing environments.

Numerical simulation of helical magnetohydrodynamic turbulence
Journal of Fluid Mechanics, 1978The three-dimensional incompressible magnetohydrodynamic (MHD) equations for rectangular geometry and periodic boundary conditions are solved numerically using the spectral method of Orszag & Patterson (1972). The calculations are restricted to a magnetic Prandtl number of one and to Gaussian random initial conditions with zero mean magnetic and ...

Magnetohydrodynamic simulations of edge poloidal flows
Nuclear Fusion, 2012Abstract Edge poloidal flows exceeding the poloidal sound speed lead to the formation of a pedestal structure (Guazzotto and Betti 2011 Phys. Rev. Lett. 107 125002). This result is based on the existence of ‘transonic’ equilibria, in which the edge region of the plasma flows supersonically with respect to the poloidal ...

Global magnetohydrodynamic simulations on multiple GPUs
Computer Physics Communications, 2014Abstract Global magnetohydrodynamic (MHD) models play the major role in investigating the solar wind–magnetosphere interaction. However, the huge computation requirement in global MHD simulations is also the main problem that needs to be solved. With the recent development of modern graphics processing units (GPUs) and the Compute Unified Device ...

Numerical simulation of turbulent magnetohydrodynamic flows
32nd AIAA Plasmadynamics and Lasers Conference, 2001The effect of magnetic fields on turbulent flows is investigated. The turbulence models that evaluate the turbulent viscosity must be modified in the presence of a magnetic field. Computations of a turbulent flow field over a flat plate at Mach 2.0 with the Baldwin-Lomax and k-e models have been performed.
