Hi!

I'm working on a conjugate heat transfer problem where I will have a fluid inside a pipe which will work as a coolant, and a heated area where the outlet is, which is heating up this pipe wall. Along the pipe (close to this heated pipe wall) there are 3 heatsinks attached.

It is my first time doing a conjugate heat transfer problem and I am struggling with the boundary conditions. Now I have mass-flow inlet with an inlet temperature, and a pressure-outlet with no reverse flow. At the outlet pipe wall, I have set a direct temperature on the wall under thermal conditions->temperature (is this correct?), but what do I set on the rest of the pipe walls and the heatsinks? There is a temperature outside the pipe that I want to be included in the heat transfer analysis. I don't know any heat fluxes or the heat transfer coefficient.

Would really appreciate if someone had time to point me in the right direction
