Hey guys,

I'm new to OF and my problem is the following:
I want to simulate a circuit board and the induced flow inside a casing including radiation.

I have already calculated the powerconsumption over the board in Watt and created a "heatmap" (powermap) over the board.
Now i want to use this powermap to simulate the induced flow due to convection incl. radiation (not neglectable) inside a given casing.

My questions now:

1) Searching the web i found this (http://www.tfd.chalmers.se/~hani/kur...Foam_final.pdf) but i have no idea how to implement it.
Is there a free showcase to download and to play around with?

2) Has somebody simulated a similar case?


PS: I also tried SimScale and i was able to simulate the convection but without radiation. I recommend SimScale for a case without radiation due to it's easy operability and the wide collection of tutorials.

Hi,

Start simple.

Refer to:
1. $FOAM_TUTORIALS/heatTransfer/buoyantSimpleFoam

2. $FOAM_TUTORIALS/heatTransfer/chtMultiRegionSimpleFoam

try running a couple of test cases.
