Hi all, 

I am trying to do a simple convective heat transfer using the following concept

So basically the heat comes from all the external surfaces of the polystyrene as well as the steel cladding.

I wanted to simulate the convective heat transfer that is happening inside this box.

In the image, you can see two fluid domains called "air". I wanted to examine the temperature of these two. 

 

The thing is, most of the tutorials on the internet do not show how I can achieve this. Because the steel cladding will radiate the heat to the first layer of air, then it affects the temperature of the polystyrene in the middle of the structure, then ultimately affects the heat of the bigger size of air. I am not sure if I am explaining this clearly.

Is fluent capable of doing this? What is the general workflow that I needed to follow to achieve the simulation?

Here is another image in case the first one is not clear

Also, if it is just a 2D convective heat transfer with just one fluid zone, I can easily do that like this

 

But the thing is I am not sure how to do a more complex simulation like the one I mentioned.

Kindly let me know if you have any insight on this

 

Thank you

Hello,

Yes, you can do it in Fluent. Create seperate cell zones for solid and fluid and ensure the option of Participates in Radiation is turned ON in solid cell zone, in case you need radiation in solids. You can also add the heat source in the fluid and solid cell zones.
