Heat exchange

Asked by Ed Carlos Alves Rocha

Hello everyone!

I have a problem, I would like to do one simulation with heat exchange.

The simulation it's about a hot wall, heated wall with resistance/ induction, where the particles heat exchange considering only the conduction.

1) How to give the input of the coefficients of conductivity and specific heat of the particles?

2) How can I give the input of the wall temperature?

3) How to activate heat exchange?

Hello Ed,

YADE does not currently support thermal processes. But the code is flexible enough that someone (you?) could code it and share it with the community.

Cheers,

Robert

Thank you Robert,

for me it is a great challeng.

I will read more information and do something and share with the yade community if I can do anything.

Anyone know about any article to get started?

Regards,

Ed

Here is a good paper for establishing conduction between discrete particles:

Feng, Y. T., Han, K., Li, C. F., & Owen, D. R. J. (2008). Discrete thermal element modelling of heat conduction in particle systems: Basic formulations. Journal of Computational Physics, 227(10), 5072-5089.

And, here is a follow-on paper to the one posted by Robert and by the same authors. The approach proposed in this paper is applicable for transient problems as well.

Y.T. Feng, K. Han, D.R.J. Owen,
