CHT - Temperature/ Heat source issue

I am analyzing heat transfer of a battery pack through. A heat source of 2.75w is applied per cell.
when the simulation is completed, there is barely any change temperature.

Can anyone help me regarding this issue?

Thank you

Hi there, this is Fillia :slight_smile:

There is some temperature change, of course, it is not significant, but if the conditions changed, you would see a greater difference.

I have a couple of comments:

  1. Have you checked whether the flow is actually turbulent?

  2. Try to increase the dimensions of the domain across the y-direction. You can use Figure 8 from this tutorial as reference: Compressible Flow Around a Wing | Tutorial | SimScale

  3. If the domain does not represent a closed box, switch the “No-slip walls” to “Natural convection inlet/outlet”.

Best regards,
