Heat exchanger design

libya81 · April 14, 2012, 01:15

Hi there,
My project is to design two pipes one in side the other. I have drawed 4 skeches, one for the inner pipe, one for the inner pipe's wall, one for the outer pipe, and the last one for the outer pipe's wall. After that, I have created a surfaces for each one. Finally I have cut the first sketch by using a Boolean option and then subtract.
Do you guys think I am on the right track, or I have to create the fifth sketch, or I am totally designing a wrong geometry.
Best
Thanks in advance

Hi!

I am not sure if it is precisely what you want, but the following tutorial you might find useful.

Hi,

I think the best way is first to create a volume which includes all your geometry (namely a cylinder of the same size of your outer pipe) and then splitting it using internal surfaces (to create all the internal domains you need).
I find out this is the best way to make fluent recognize well the interface surfaces between the different volumes.

Hope this can help
