Hello,

I have the following problem: there is a copper pipe getting through a wooden wall. On one side of the wall (hot side), I have elevated temperature which is defined by radiation and convection. On the cold side I have ambient temperature, again defined by radiation and convection (picture in the attachment). It should resemble the experiment done in oven.

However, between the wooden wall and the copper pipe there is a little gap which (in reality) lets some of the hot gasses to pass from one side to another. So far, the temperatures on the cold side are much lower comparing to the experiment.

Is there any way to simulate this stream of hot gasses getting though the gap around the pipe and how to do it? Or if I am doing something completely wrong with defining the parameters?

Thanks.

I think your observation is correct. And certainly you can model the flow through the gap if you know the pressure difference or the amount of gas passing the gap. You can do it using CFD and this is a CFD-forum. So you are on the right spot. But why your question? You don't know how to do it?
