CFD Simulation of Flow Through a Pipe in an Air Domain
I want to simulate a pipe (with an inlet and outlet) inside a large air domain. In addition, I want the pipe walls to provide heat to the flow inside the pipe. So the flow at the outlet is at a higher temperature than the flow at the inlet. I then want to see how the hot flow at the outlet interacts with the air domain.
When I set this up, I am unable to obtain an "Inlet" for the pipe inside the air domain. Could you please advise? The air domain is supposed to be stagnant, and then the pipe inlet sucks in air at a velocity that I want to specify. The air then goes through the pipe, becomes warm, and I want to see how the warmer air interacts with the air domain surrounding the outlet. How do I go about setting this up so that I can successfully obtain a pipe inlet boundary condition inside Fluent?
