I am trying to run a simulation with two identical fans operating in parallel, pulling air through an enclosure. In theory, this should double the volumetric airflow through the enclosure. However, what I am seeing is one fan operating on its fan curve at an expected p and Q, while the other fan is effectively not functioning. It's p value is high and the Q value very low, and the values are not even on the fan's operating curve.
I have double checked all boundary conditions, input flow directions, and materials. They are all as they should be. Have you ever observed this in your models? What is causing this? How do I fix it?
I would suggest that you check out the following first:
Thanks!
