Introduction3:25
This video introduces you to the course to learn the simulation methodology of electric arcs through the software ANSYS-FLUENT, and the MHD module
1. What is the electric arc?10:04
In this first video we will talk a little about what is an electric arc and its formation, taking as an example the case of arcs in Circuit-Breakers.
2. Electric arc physics24:33
In this part we will know the multi-physics that governs the electric arc, current interruption methods and an introduction to the magneto-hydrodynamic theory.
3. Simulation model16:36
In this part we will know the model used for simulations, geometry, mesh and boundary conditions.
4. Module MHD and UDF´s12:23
In this part we will know how to compile the UDF´s in FLUENT, and the equations for each property of the electric arc. Such ach (density, electrical conductivity). Also the coding of this UDF´s in C++.
Adding to this we will know the steps to activate the module MHD in ANSYS-FLUENT.
5. Methodology for simulation in ANSYS-FLUENT34:54
In this part we will know the set up in MHD module and the exact steps for a simulation. This is the most important part of the course.
5.1 Solution errors56:29
Solution for simulation errors
6. Obtaining and interpreting results11:29
In this part we will know to interpret the results of the temperatures, voltages and currents obtained in the simulations and create some animations.

Description

In this course you will learn the methodology for simulation of electric arcs through the software ANSYS-FLUENT. You will learn all the necessary steps for the activation of MHD module, geometry, mesh, simulation and interpret the results. In addition to knowing about the theory of electric arc and ways of applying it in other models that involve electromagnetic phenomena. You will find an example of simulation and the results.

The MHD module is a really useful tool which allows to coupling the Navier Stokes equations with the Electromagnetic equations, and in this way simulate a fluid with magnetic properties. And this module not only allows to simulate electric arcs but also any can of ferromagnetic fluids.

In this course you will find all the necessaries steps for the simulation and the codification for UDFs in C++, and in this way you can modify it. You can applied this methodology in 2D and 3D models, and in models with dynamic meshes as well.

When you finish this course you will be able to do your own arc simulation, and I suggested to start with the model developed here, then you can move to more complex ones. If you have any doubts you can write an email.

Who this course is for:

Researchers focused on simulations in ANSYS, fluid mechanics, heat transfer
Researchers focused on electromagnetic phenomena
