Dear friends,
I am using FLUENT for simulating a continuous casting problem. In fact, I want to repeat the simulation given in the following paper at the first stage, without considering the segregation problem(just flow and solidification): http://www.springerlink.com/content/u159222514283281/ The simulated length of caster is 3m, with mold length of .5m, mold diameter of 11.5cm, nozzle diameter of 3cm, and casting speed of .01m/s. I am using a 2D mesh as the casting part is a round billet. I have modeled the case in FLUENT, but there are some problems: 1- The steady solver doesn't work at all, it diverges quickly. I have played with initial condition and UDFs, but I couldn't fix it. Note that the paper I mentioned solved the steady equations. 2- The unsteady solver works fine, but the system does not become steady as expected. I continues cooling and solidifying as the simulation runs. This is not correct, as I guess at about the lenght 2.5-3m the complete solidification should occur. 3- I don't know how to set the outlet boundary condition to what the paper says, i.e. letting all normal gradients to zero. I used a "velocity inlet" boundary condition with x-component velocity set to casting speed. I had played a lot with problem changing many parameters. But there were no success! Do you have any idea to fix the problem? And, how should I set the zero-gradient outlet boundary condition? And, does anyone has an example of similar system in FLUENT which can send it to me? Very thanks. Luke Christ luke.christ23@gmail.com |

Dear Luke Christ,
I am also trying to model the similar problem (segregation during Continuous casting). Is it possible to model the paper http://www.springerlink.com/content/u159222514283281/ using FLUENT. I have just started my work, can you please share your experience in modeling solidification in continuous casting using FLUENT. Thanks, Niranjan Reddy Ch. |

Hi
Just a quick question, have any one ever used ANSYS fluent for modeling segregation in continuous casting?? I'll be appreciate if any one help me with the problem... Here is my E-mail : tuv989@gmail.com Thanks Last edited by M.Panther1989; May 9, 2013 at 15:07. |

I am involved in a similar project. Did you finally figure it out ?

I also encountered the same problem recently. I am not sure if I can solve the segregation phenomenon with fluent, because I am a beginner. If possible, can you send me a copy of your segregation materials or tutorials, I am very grateful! Here is my E-mail : qinhuaxie095@gmail.com Best wishes! |
