Hi Everyone,
I'm fairly new
Hi Everyone,
I'm fairly new to OpenFOAM and I am having troubles in setting the boundary conditions for a simple test case in potentialFoam. I'm trying to simulate external flow over a NACA airfoil at 14 degrees AOA. I don't have any problems in obtaining a solution with potentialFoam, icoFoam or simpleFoam when the angle of attack is low (0 to 5 degrees). However, for large AOA, there is an outflow on my INLET patch and it seems to cause problems. My mesh is a C-mesh (it can be viewed at NACA0012 mesh ). The INLET patch is the patch on the left (C-shaped) and the OUTLET patch is the patch on the right. My boundary conditions are as follows: U: INLET type inletOutlet; value (40 10 0); OUTLET zeroGradient; p: INLET type outletInlet; outletValue 0; OUTLET fixedValue; value 0; The velocity field I obtained can be seen here: velocity field 1. I also tried the following: U: INLET: fixedValue (40 10 0) OUTLET: zeroGradient p: INLET zeroGradient OUTLET fixedValue 0; But then I get the following: velocity field 2. Like I said, I don't have much experience with boundary conditions in OpenFOAM so I was wondering if anyone could help me. Thank you for your time Patrice |
Hi Patrice Castonguay
Hi Patrice Castonguay
This venkatesh from india i am working on NACA0012 Airfoil which is imported from fluent. Now i need to solve it for Euelrs equqtions with incompresible flow can u tell me procedure for that with mach number .85 |
hi venkatesh,
instead of usin
hi venkatesh,
instead of using fluent file u can use .msh file from gambit and change to foam format by using fluentMeshToFoam command which will change the gambit mesh file to foam mesh file. then u can copy simple foam folder in ur login name folder there u will get boundary file inside ur control folder. copy that details in ur 0 file and edit ur boundary condition .it ask there for how much mach no ... try this out iof any prob mess me back |
HI Patrice Castonguay Sir
HI Patrice Castonguay Sir
This is Venkatesh from india working on NACA0012 AIRFOIL can u please send me the procedure u solved for the 0 - 5 AOA......... |
