Magnetohydrodynamics Definition and 17 Threads

Hello everyone, This is my first post on this platform, I'm excited to be a part of this community! I'm currently doing a research project on Nuclear Fusion, and have been recently introduced to the concept of Magnetized Linear Inertial Fusion (MagLIF). I'm still new to the topic of...

Hello, I am trying to create a MHD boat. With my magnet and my generator, which generates a current of 10A, I can create a rapid flow. However, the cable connecting the electrodes to the generator generates a force that prevents my boat from moving forward. I've tried different types of cable...

I am attempting to derive equations of state for a flow loop that incorporates a magnetohydrodynamic (MHD) generator to extract energy from the working fluid, an ionized gas. I have been able to find the following equation to define the power output of the generator: (where K is load factor, σ...

According to the MHD theory, is case of energy production, a magnetic appplying a magnetic field to a moving charge perpendicular to the magnetic field, that could be plasma as well a solution full of ions, and placing two plates, electricity could be produced. Now I have a question, let's say...

Force free: ##\mathbf{J} \times \mathbf{B} \sim (\nabla \times \mathbf{B}) \times \mathbf{B} = 0## (N.B. MHD applies so ##\epsilon_0|\partial \mathbf{E}/\partial t|/|\mathbf{J}| \ll 1##). Axisymmetric: can write ##\mathbf{B} = \nabla \psi \times \nabla \phi + B_{\phi} \mathbf{e}_{\phi}##...

I'm currently searhing for a magnetohydrodynamics simulator to study how different molten metals interact with variating magnetic fields, is there any free (preferebly) simulator that someone recomends in particular? And also, is there any way to use Autodesk's CFD to create a MHD simulation?

Summary:: partial differential equation (PDE) to describe the potential distribution φ in the system Hey, I need some help with the following question: We have a stationary electrolyte, a magnetic field "B" and a Current density "j" (2D). Derive the partial differential equation (PDE) to...

Homework Statement:: Simualte the behaviour of water around an mhd inductive thruster Relevant Equations:: https://www.comsol.fr/paper/download/45837/Pintus.pdf Where can I start this simulation ? What is the required software ? [Mentor Note -- thread moved from the technical forums]

Hey guys. I wanted to ask your opinion about something . I'm interested in MHD propulsion and i know so far that has been inefficient against the usual propulsion systems up to today. Do you think it worths someone getting deeper into it ? I'm thinking how awesome would a practical...

Hi guys I'm finishing up some promo art for my original comic book. You're seein it here first. But its missing something- an appropriate equation. I would like to integrate a math equation into the art. I am attempting to depict FTL travel, using qualities similar to an LWFA, the plasma being...

I have a question which puzzled me when I was reading up about auroras. When talking about the interaction of the solar wind and the Earth's magnetic field, the book said that "particles are accelerated along magnetic field lines towards the earth" That didn’t sound quite right, as I was taught...

Hey, I was trying to find out how to calculate velocity of water through a magetohydrodynamic thruster given current, dimensions, pure water etc and google did not help me in my search, any help appreciated.

I've been reading some about the ITER project, tokamaks, and other approaches to plasma containment. Why can't ion trapping approaches such as an orbitrap be used for fusion plasma containment?

Sorry, I am not a physics major - I apologize in advance if this question is ignorant or if this was asked already. What would be the most effective as a Magnetohydrodynamics weapon? Assuming normal ionized air, would a liquid (liquid silver and salt water) or some type of plasma...

Hello all, I was going to buy this book. https://www.amazon.com/dp/0486450325/?tag=pfamazon01-20 Has anyone ever used it? If you have used it, is it worth purchasing? Thanks Matt

Hi guys, I am simulating a flow of ferrofluid in the fluent software.Since ferrofluid does not conduct so the it may not be categorized as magnetohydrodynamic (MHD)flow.As far as I know it is called ferrohydrodynamic flow. Now this requires a body force term in fluent...I am relatively new to...
