Boundary conditions for inlet and outlet of fluid flow in a tube

Hello,
I am trying to simulate a heated tube (solid region) in which a fluid is flowing inside (fluid region). I am using openFoam version 6 and the chtmultiregionfoam solver. The fluid enters the tube at the inlet with a certain initial temperature, flows through the tube, reaches the outlet of the tube, and comes back in a sinusoidal fashion. So it means that once the fluid enters the tube, it remains inside and it moves back and forth. It interacts with the tube walls (which are heated) so the fluid will heat up and increase its temperature. (please see the picture) The fluid has a certain inlet temperature and inlet velocity but with time it should absorb the heat generated by the solid region. What should be the boundary condition for the fluid (p, T, U, prg, etc.) at the inlet and outlet? tube1.png |
