This is my combustion chamber wall temperature contour. Now, i want to extract the heat convert to electric by using thermal-electric simulation. 
1) I need to transfer the contour data to another surface. I need to some how map the contour of the wall temperature to the another surface so that i can obtain the temperature of the hot side. Somehow i need to transfer contour data from fluent to mechanical. (pic below can describe)

so my question: is there any alternatives i can do this so that i can mapped the temperature contour of the combustion chamber wall to the thermoelectric generator inner surface which is the hot side of thermoelectric generator or you have better suggestion or way to this simulation. Very appreciated your advice.

Hi

You should be able to drag and drop from a Fluent system (Solution cell) to the Thermal Electric System (Set up cell) say in 2023 R2.

In that system you can then add: Imported Load (Fluids Results File) and a temperature load import.

See here for this workflow - it is for steady state but should be similar for thermal electric.

Otherwise external data can be used.

Hi, thank you for your reply. 

Is this what you mean draw one more geometry for thermoelectric generator layer like i show in the pic below and then run it again in fluent together with the thermoelectric generator layer to capture the temperature profile. can i do this way?

i think i want go with external data approach. can you teach me how to export data file in csv in fluent because i couldn't make it even with the video tutorial on youtube.

Hi

This is fluent related.

See/post the fluids forum.

This post might also be of help:

All the best

Hi there, can i know why this happen, is it normal, why the value heat absorbed at hot surface is same as the heat released at the cold surface but opposite sign? 

[Foo Sin Khai]

This is the geometry and the setup including the engineering data setup. Can you help me to see whether where the issue come from? Because like i mentioned earlier the heat absorbed and released is the same. I would expect there is difference between this two value. And my final aim is to find the electrical power generated. Do you have any suggestion on how to calculate the electrical power generated on converted from this TEG based on my model here?

Hi there, anyone can help with the problem here?

Hi, Erik. Do you have any suggestion how to solve the problem here?
