turbulent channel Flow - simpleFoam
1 Attachment(s)
Hello Foamers,
I want to compare the result of turbulent and laminar channelflow from Fluent and OF. Im using the simpleFoam-solver and the resulats of the laminar flow are looking fine. Now i just want to run the same case with higher Re. So i just copied the case, calculated k and epsilon link in the OF User Guide and started the case. The results seems to be wrong: e.g. the inlet velocity is set to 7.5cm/s, but v_max is just like 7.5432 cm/s. That seems quite strange to me... I attached the case, it would be great if someone could help me.. Thanks a lot, have a good day.. Michel |
HelloMichel,
I am no expert in this but there is an example in the Programmer's guide to carry out a turbulent flow analysis in backward facing step using simplefoam, did you go through this? How did you get the laminar results? did you use simplefoam? Thank you Naveen |
BFS is steady state or transient
simpleFoam is steady state and pisoFoam is transient.
Is it possible that turbulent backward facing step be steady state? i saw pitzDily which is same as a BFS in pisoFoam tuturial. please tell me how can a turbulent flow in BFS with its deifferent eddies can be steady satate? Thanks. |
