Hello all
I'm modelling a wind tunnel which has a converging-diverging nozzle upstream of the test section. At the moment, the flow almost reaches the target of Mach 2, but what really stumps me is that it becomes sonic not at the throat but a couple of cm downstream. I've attached some screenshots, as well as the report from CFX-post. If anyone has any ideas I would be grateful for your support. Thanks Max |
