Hello all
I am working on a conjugate heat transfer problem with a hollow cylinder with the following details:
1- The inner surface of the cylinder is heated by induction;
2- The outer surface is surrounded by a a metallic block which contains some channels for water flow for purposes of cooling the outer surface.
My questions are:
1- What is the best way to represent the induction heating in simulation ( Heat generation rate or heat flux or whatsoever...)
2- The contact between the cylinder outer surface and the cooling block, how can be dealt!
Thanks in advance
Mohamed
1- The answer to this question depends on the physical phenomenon of the induction heating process. Do you have any more details about this process to give us?
2- I would start the model with an ideal situation, where you have perfect surface contact with the two material. This is the simplest model, just you create your CAD geometry with the two parts sharing the same dimensions at this contact. In reality of course this will not be so nice, you will either have a metal to metal contact with it's associated thermal resistance, or you can use a thermal interface (such as the paste used for heatsinks) which you can model as a contact resistance in the software.
