 April 3, 2009, 05:54 Continuous casting simulation problem #1 New Member   Luke Christ Join Date: Apr 2009 Posts: 7 Rep Power: 8 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

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.

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.
