Hi,
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. |

Hi,
have you solved your problem? If not it would be helpful if you'll post some pictures of your geometry and your mesh. cheers wikie |
