In physics and engineering, magnetohydrodynamics (MHD; also called magneto-fluid dynamics or hydro­magnetics) is a model of electrically conducting fluids that treats all interpenetrating particle species together as a single continuous medium.

磁流体力学 （英文： MHD, Magnetohydrodynamics 、 magnetofluiddynamics 或 hydromagnetics），是研究 等离子体 和 磁场 相互作用的 物理学 分支，其基本思想是在运动的导电流体中，磁场能够感应出 电流。 磁流体力学将等离子体作为连续介质处理，要求其特征尺度远远大于粒子的 平均自由程 、特征时间远远大于粒子的平均碰撞时间，不需考虑单个粒子的运动。 由于磁流体力学只关心流体元的平均效果，因此是一种近似描述的方法，能够解释等离子体中 …

Magnetohydrodynamic (MHD) (magnetofluid dynamics or hydromagnetics) is the study of the dynamics of electrically conducting fluids. Examples of such fluids include plasmas, liquid metals, and salt water or electrolytes.

2021年12月1日 · In this paper we review and summarize features of 2D and 3D MHD flows that are typical in liquid metal blankets, together with available correlations for MHD pressure losses.

2024年3月12日 · This paper studies the transient MHD flow around a porous material passing through an ascending perpendicular plate. The medium appears as a grey fluid that absorbs radiation but does not scatter. This model is based on nonlinear differential equations.

2024年4月1日 · In liquid metal (LM) magnetohydrodynamic (MHD) flows in the access ducts of a breeding blanket of a fusion power reactor, the spatially varying fringing magnetic field can be responsible for high MHD pressure drop, which is one of the blanket feasibility issues.

In this example we shall investigate the flow of an electrically-conducting liquid through a magnetic field. The problem belongs to the branch of fluid dynamics known as magnetohydrodynamics (MHD), simulated using the mhdFoam solver.

2024年2月14日 · In the present study, we investigate numerically liquid metal MHD flows in the pipes, which cross the shield that protects the superconducting magnets from neutron radiation-induced damages. The geometry features two bends in series that turn the flow from the radial direction perpendicular to the magnetic field into a direction parallel to it ...

2020年3月12日 · A comprehensive investigation of mass and heat transfer in magnetohydrodynamics (MHD) flow of an electrically conducting non-Newtonian micropolar fluid because of curved stretching sheet is...

2019年1月30日 · Magnetohydrodynamic (MHD) is the study of fluid flow in electrically conducting fluids with magnetic properties that affect fluid flow characteristics. When a magnetic field is incident in an electrically conducting fluid, a current is induced.
