Magnetohydrodynamics (MHD) is the study of the behavior of electrically conducting fluids (like plasmas, liquid metals, or saltwater) in the presence of magnetic fields. The term itself combines "magneto," referring to magnetic fields, and "hydrodynamics," which is the study of fluids in motion. MHD involves the interaction between the fluid's motion and the magnetic field, which can significantly influence the flow behavior.
Alfvén's theorem is a principle in plasma physics, specifically within the context of magnetohydrodynamics (MHD). It describes the behavior of plasma in the presence of a magnetic field and is named after the Swedish physicist Hannes Alfvén, who received the Nobel Prize in Physics in 1970 for his work in this area.
The Grad–Shafranov equation is a partial differential equation that arises in the study of magnetically confined plasmas, particularly in the context of magnetohydrodynamics (MHD) and plasma physics. It describes the equilibrium state of a plasma in a magnetic field under the influence of pressure and other forces.
The Hartmann number (Ha) is a dimensionless quantity used in magnetohydrodynamics (MHD) to characterize the behavior of electrically conducting fluids in the presence of a magnetic field. It is defined as the ratio of the magnetic force to the viscous force acting on the fluid. The Hartmann number is an important parameter in studies involving the flow of liquid metals, plasmas, and other conductive fluids in magnetic fields.
The induction equation describes how the magnetic field evolves in magnetohydrodynamics (MHD), which is the study of the dynamics of electrically conducting fluids. The induction equation is used to determine how magnetic fields change in a fluid that is also influenced by electrical conductivity and fluid motion.
The Magnetic Prandtl number (Pm) is a dimensionless quantity in magnetohydrodynamics (MHD) that characterizes the relative importance of magnetic diffusion to momentum diffusion in a conducting fluid.
The Magnetic Reynolds number (Rm) is a dimensionless quantity used in magnetohydrodynamics (MHD), which studies the behavior of electrically conducting fluids in the presence of magnetic fields. It characterizes the relative importance of advection of the magnetic field by the fluid flow to the diffusion of the magnetic field due to electrical resistivity.
Magnetohydrodynamic (MHD) turbulence is a complex field of study that combines aspects of fluid dynamics and magnetohydrodynamics, which is the behavior of electrically conducting fluids in the presence of a magnetic field. MHD turbulence is particularly relevant in astrophysical contexts, such as in the behavior of plasmas in stars, galaxies, and interstellar space, as well as in industrial processes involving liquid metals and other conducting fluids.
"Magnetohydrodynamics" is a scientific journal that focuses on the study of magnetohydrodynamics (MHD), which is the branch of physics that deals with the behavior of electrically conducting fluids in the presence of magnetic fields. This field has applications in various areas such as astrophysics, space physics, engineering, and geophysics. The journal publishes original research articles, reviews, and other contributions that explore theoretical, experimental, and computational aspects of MHD.
