SUMMARY

This discussion focuses on simulating ferrofluid flow using ANSYS Fluent software, specifically addressing the distinction between ferrohydrodynamic (FHD) and magnetohydrodynamic (MHD) flows. The user seeks to incorporate a body force term for FHD in Fluent, indicating the necessity of a user-defined function (UDF). Additionally, the existence of an MHD module in Fluent is confirmed, which may be relevant for simulating FHD flows, although the user must adapt it for their specific needs.

PREREQUISITES
  • Understanding of ANSYS Fluent software
  • Familiarity with user-defined functions (UDFs) in Fluent
  • Knowledge of ferrofluid properties and behavior
  • Basic principles of fluid dynamics and magnetohydrodynamics
NEXT STEPS
  • Explore the ANSYS Fluent MHD module documentation
  • Learn how to create and implement user-defined functions (UDFs) in Fluent
  • Research the physical properties and modeling techniques for ferrofluids
  • Investigate the differences between FHD and MHD flow simulations
USEFUL FOR

Researchers, engineers, and students involved in fluid dynamics, particularly those focusing on ferrofluids and magnetohydrodynamics using ANSYS Fluent.

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.
