Description
technical field [0001] The invention relates to the field of numerical simulation calculations, in particular to a numerical simulation calculation method based on the FLUENT MHD module. Background technique [0002] The discipline that studies the motion of conducting fluids in electromagnetic fields is called magnetohydrodynamics, or magnetohydrodynamics. Compared with fluid mechanics, the outstanding feature of magnetohydrodynamics lies in the interaction between current and magnetic field, including the interaction between current and magnetic field caused by the movement of conductive fluid, the Lorentz body force that changes the fluid movement, and the change caused by current. The induced magnetic field of an electromagnetic field. [0003] The basis of the MHD theory is the fluid dynamics equations, Maxwell's equations, and the relationship between the two through Ohm's law, Lorentz force and Faraday's law of electromagnetic induction, that is, the MHD equations. ...
