Working on an analyis for a nozzel that uses an air amplification scheme.
The velocity magitude seems as though it is correct, but the flow rate through seems almost negative.
See pictures below - any thoughts are welcome.
Just a remind the tips at inquiring flow rate in POST processor
- Change result to flow rate
- Select interested surface(s) only or face(s) at interested elements
(Never select nodes)
- Make sure result smooth is disabled
BTW, the negative flow rate is probably correct depending the inflow or outflow at selected surface(s).
