hello everyone. I am trying to analyze an tested centrifugal fan with cfx. CFX results are 20% lower than the test results at high pressures and close to the test results at low pressures. I tried all input and output combinations but the results did not change. I ran it with transient and the results are still incorrect. When I looked at the flow with the cfd post, I noticed that there was a reverse flow in front of the wing. Where do you think the problem might be? The photo about this is attached.
