Simulating rubber viscosity variation
The curing of rubber is better known as vulcanization, this is a process in which rubber is heated resulting in viscosity changes of the rubber as the molecules react and form bonds (cross-link). When the rubber is initially heated its viscosity decreases and at a certain point it starts to flow, some time after this the viscosity starts to increase (as cross-linking occurs) and the rubber starts to solidify up till the point it is solid rubber.
I am very confused on how to start with a simulation like this and would appreciate any help available from other users within this forum.
Are there any standard solvers which I could use to simulate this within OpenFOAM?
If you have any information which may help me in any way with this simulation please let me know.
did you read http://www.cfd-online.com/Forums/ope...fluidfoam.html
Jovani L. Favero implemented Maxwell, Oldroyd-B, Giesekus, PTT linear and exponential,
FENE-P, FENE-CR and DCPP. There are others models already implemented but not tested (Pom-Pom, SXPP, DXPP, WM ...).
Maybe this contribution can help you
Thank you for the link, unfortunately it does not contain the curing of the material therefore it can not be used for my simulation.
I now have a better understanding of the problem and I will create a new thread describing the new problem.
