Ferrohydrodynamics and magnetohydrodynamics

[souviktor]

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 fluent...whatever impression I have got so far is that to incorporate the Ferrohydrodynamic body force term in the momentum equation I have to use a user defined function.
My question is there is a MHD module in fluent.Can I use it to simulate FHD flows?

Hello,

I just came across this post when I was searching for mangetohydrodyamics and yes there is a FLUENT MHD module.

Here is the link to the manual.

Hi there,

Thank you for sharing your simulation work on ferrofluid in the fluent software. Ferrohydrodynamics (FHD) and magnetohydrodynamics (MHD) are both fields of study that involve the interaction of fluid flow with magnetic fields, but they have some key differences.

FHD deals specifically with the behavior of ferrofluids, which are liquids that contain magnetic particles. These particles can be manipulated and controlled by an external magnetic field, and their presence can significantly alter the fluid's flow behavior. On the other hand, MHD deals with the behavior of electrically conductive fluids, such as plasma or saltwater, under the influence of magnetic fields.

In your simulation, it is correct that you would need to incorporate a body force term in the momentum equation to account for the presence of the ferrofluid. This can be done through a user-defined function, as you mentioned. As for the MHD module in fluent, it is designed specifically for conducting fluids and may not be suitable for simulating FHD flows.

I would recommend consulting with a fluid dynamics expert or the fluent software support team for more guidance on incorporating the ferrohydrodynamic body force term into your simulation. Best of luck with your research!
