moving airfoils very immediate

hsn · July 24, 2009, 02:06

hi
I have a problem and I will be very thankfull if any1 help me.

consider a problem in that we have 2 airfoils near each other and we want to view the influence of movint one of them on the other. I mean one of them will change its angle for example.
1-can this problem be solved by a cfd approch?
2-Is this a transient problem?
3-what can i do with the mesh? (is a movable mesh a good idea? how?)

regards.

If you are mainly interested in lift force and pressure drag (no viscous drag) away from the stall condition then you might consider a panel method. Panel methods only require a surface mesh so the movement part is relatively easy compared to general field methods that require a volume mesh.

[Marketing] Here at Symscape we have a transient 3D panel method with rigid body motion that may suite your needs.
