Temperature variation within thermocouple in Seebeck mode

[elt93]

Hi guys,
I posted a thread a while ago asking for advices to create a Finite Element model of a radioisotope thermoelectric generator. I've basically finished this model mainly using conduction and radiation at the boundaries. I am wondering something though: currently my heat gradient is very low between the hot and cold junction ~5 K. Would it be worth coupling the temperatures inside the thermoelectric device with the thermoelectric effects knowing that it will complicate a lot the model or will the effects be really small and not worth it ?
Thank you for your help!

I have notified the owner of www.pyrosales.com.au about your question and hopefully I will be able to provide you with some important info/feedback.The owner is John Shanahan.

Hopefully this is OK with the website and Greg.
