Uncoupled heat transfer analysis
Uncoupled heat transfer analysis
(OP)
I have a pipe that the product inside is 60oC. half of the pipe is in the water which is 4oC. and half in in the air which is 22oC.
How should I apply the boundary condition to the 3 surface of the pipe (inside pipe, outer pipe in water, outer pipe in air)? in order to output the temperture within the pipe for the stress analysis.
should I apply by BC - surrounding temperture?
or Load - surface heat flux?
If I need to apply as surface heat flux, how can I calculate it please?

If I have to consider flow rate inside the pipe, why do i not needed for the water?
If I samplifer the problem by applying temperture to the surface that touch the water and the inner pipe that touch the product. How wrong is my results (assuming the maximum temperture different is only 60oC)

If you're not sure then take the worst case possible for maximum stress. In this case that would be maximum temperature differences either through the thickness or mean temperature differences. If your stresses are acceptable for the worst case then a lesser more realistic but unkown case, would also be acceptable too.
