I am trying to simulate a train exhaust plume system in the open-atmospheric condition.
What boundary condition would be more appropriate to set in a “sky boundary section”?.
I usually set a wall or symmetry. But now I want to setup an open-atmospheric condition.
Do you have any suggestion?.
What you can do is to either increase the box so that it does not influence the flow on the top or use the freestream velocity BC for your faces and set them to a value according to your needs. Hope that makes sense!
I am trying to simulate the how exhaust plume affect the inlet vent. The main issue in this project is 2 x inlet vent very close to exhaust vent. Attached my model picture.
