Difficult inlet position causing problems...
I am relatively new to CFD and I have obtained Phoenics CFD software to use for my Uni Project.
I intend to model the suction that is induced around the surounding area of an outlet of a nozzle for ventilation however I am having difficulties with the nozzle inlet. The inlet is positioned at z = 0mm and after the program has run (approx 2 hrs) there is always extreme turbulance between the edge of the outlet and the nozzle wall that I am pretty sure is incorrect.
The nozzle wall is thin (1.5mm) so grid has geometric progression towards these areas. The inlet flow veloctity is 5m/s.
I have attached a pic of a program that I have just ran for reference.
Any Sugesstions would be greatly appreciated.
have you solved your problem? If not it would be helpful if you'll post some pictures of your geometry and your mesh.
