reverse flow in pressure outlet BC
hi all,
i am simulating a flow over an airfoil using LES. my BCs are pressure inlet and pressure outlet. can anybody please help me in determining the correct backflow conditions. And can anybody please tell me that what are budget terms in LES? |
If I am wrong somebody please correct me but you cannot determine backflow conditions directly.
What do you mean budget terms? Which CFD software are you using? Did you have a look at its manual? I Googled it but found no answer. |
i am using FLuent. Fluent gives us three options in a drop down list for backflow conditions when we are setting pressure outlet BC. i have consulted the manual but it dont describes it in appropriate detail. I think somebody who have experience using this BC can guide me better than the manual. If you can please guide me on this.
