Hi KyleL
As I said I am interested in. I had some literature review. Did you have too?
What is your plan?

Ata,
I guess my plan is to first find out what if any development has been done? Then I would like to review any information available, and maybe find a programmer that would be willing to help develop the needed moldFOAM solver.
I would very much like to see any information you have available.
Thanks,
KyleL

Hi Kyle Lampkin
I have some paper a bout this, but now I don't remember their title and authors and I must take a look at my resources. Do you want them? If yes I'll send them for you.
All the best

Are there any updates about this matter? I'm really interested in any applications wich involve the use of the OpenFOAM frame in simulating the injection molding process for polymers.

Thank you in advance

Hi
I have written a two phase code for polymer processing but now I am PhD student and I can not release it until the end of my PhD but if you want may be I could help you in code preparation or you can wait until the end of my PhD.
Best regards
Good luck

Hint: write a paper on it, with the details of the implementation, the numerical treatment and all the bits. It's a very good way to protect the authorship of your work.

Good luck!

Hi Alberto Passalacqua
I am doing that and after publishing my work, I'll release my code.

First of all thanks for the reply. Secondly, of course I do not ask for your source code if it hasn't been released yet (I'm a PhD student too, soo I can easily understand the importance of protect the autorship of your work). Actually at this stage I only want to understand if such a complex flow has already been approached inside the OpenFOAM frame and how, in general terms, it can be implemented. So, generally speaking, can you tell me how did you approach the problem (I mean: are the two phases isothermal or not? Did you start with modifying some pre-existing multiphase solver, such as the interFoam one? Is the polymer fluid treated as a non-newtonian one?)? Thank you and good luck for your PhD!

Hi
My code is isothermal solver for two phase flow. Two phases can be viscoelastic-viscoelastc fluids or viscoelastic-Newtonian fluids. There is about 15 constitutive models available for viscoelastic fluids in my code and geometry is general in it. I used from interFoam and viscoelasticFluidFoam solvers and combined them.
I think it is not very hard to add energy equation to may code.
Thank you very much for your understanding me and my restrictions
Good luck with your PhD too

That's great! I suggested that because a lot of work is going on with OpenFOAM, at least judging from this forum, but not as many papers are around ;-)

P.S. Didn't mean to put pressure :-)

Hi
I have some students working on developing a code for simulation of injection moulding. They used interFoam and added an energy equation to the solver, part of the problem is discussed in following thread:

Adding a new temperature dependent viscositymodel?

The non-isothermal behavoiur is based on the paper:

"A novel design for hot-melt extrusion pelletizers"
Stefan Radel et. al.
Chmical Engineering Science 65 (2010) page 1976-1988

If the company involved in the project accepts, I will ask them to disclose the code and test case. However, there is still an issue about the frozen layer.

Hi Ata,

Is the melt compressible in your code? Do you take melt solidification into account in your solver? I am interested in injection molding simulation, too. Hope that we can hellp each other.

Best regards

Hi Jitao Liu
As now code is incompressible with no melt solidification. I would be very glad if I can help you and have cooperation with you.
Best regards

Hi, Ata
I want to combine the interFoam and viscoelasticFoam to simulate the polymer injection, just like i said in the other post. But in the interFoam solver, there is a "transportmodle" file in it ..., I have no idea to put the viscoelastic informations in it. How can I do? can you give me some advises on that?
If it is convenient, you are appreciated to e-mail me: skykzhang@hotmail.com

Hi
I ignored the transportmodle. Write one similar to it for your self.

ata, did you get your PhD already? you are appreciated for realseing the solver.
