How can I make a simple inductive MHD thruster in water simulation?

SUMMARY

This discussion focuses on simulating the behavior of water around an inductive Magnetohydrodynamic (MHD) thruster using COMSOL Multiphysics. The simulation aims to visually compare the performance of an inductive thruster with a conductive MHD thruster, utilizing different electrodes for the latter. The recommended programming languages for output are C for text-based files and VC++ or VC# for visual library support. The simulation is particularly relevant for applications in brine or seawater environments, as indicated by the linked resources.

PREREQUISITES
  • Understanding of Magnetohydrodynamics (MHD) principles
  • Familiarity with COMSOL Multiphysics software
  • Basic programming skills in C, VC++, or VC#
  • Knowledge of Finite Element Method (FEM) analysis
NEXT STEPS
  • Research COMSOL Multiphysics for fluid dynamics simulations
  • Learn about Finite Element Method (FEM) applications in MHD
  • Explore programming techniques in C for data output
  • Investigate the differences between inductive and conductive MHD thrusters
USEFUL FOR

Students, researchers, and engineers interested in fluid dynamics, MHD propulsion systems, and simulation techniques in water environments.

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 ?

In the paper you linked; the last line of the conclusion answers your question...
“Fluid dynamic, electrostatic and convection and diffusion analysis have been performed by means of Finite Element Method (FEM) where the 2D configuration model has been modeled using COMSOL multiphysics.”
See; https://en.wikipedia.org/wiki/COMSOL_Multiphysics
There are other FEM packages available.

But it appears you are not building an MHD generator that will employ an ionised gas as the fluid. You are simulating a propulsion motor for a hull in water, as in the fictional “Hunt for Red October”.
Such drives have been built and work best in brine, or seawater.

What do you want for output? If just text-based input and output files, I'd use C. If you need some visual library support, I'd probably use VC++ or VC#.

Please tell us more about this project, and whether we should move your thread back to the schoolwork forums. Thanks.

Yes, I actually would like to visually simulate the behaviour of an inductive mhd thruster in water in order to compare it with the conductive mhd thruster that I want to make (in terms of performance). When it comes to the conductive thruster, I think I'd use different electrodes to try and compare the outcomes. I'm trying to have some idea on the whole thing before I start off so I think it would be better to move the thread back to the schoolwork forums. Thanks.
