Hello Everyone ,
As we know that at higher angle of attacks and low Reynolds's number regimes delta wings tend to undergo oscillation about longitudinal axis , that is Rolling Oscillation . The commonly know as Wing Rock Phenomenon .
How can I go about modelling these kind of oscillations in a commercial CFD package like Ansys Fluent.
Kindly enlighten me with your kind suggestions .
Regards
Hi Dear Aamir
Try spallart-allmaras turbulence model.
Best regards
Hello Aamir,
You should be able to model this kind of cases by some tools available in Fluent. If you are after a 2-way coupling, so, the "MpCCI from Fraunhofer SCAI" external software tool to be used and would be the best option. However, if you expect a small structural deformation, I would suggest the "FSI mapping" toolkit which does not need any external tool as in 2-way coupling.
I hope this helps
Best regards
Hayder
Thank you so much Hayder Al-Jelawy for you kind response .
Actually I am using a rigid wing with no structural deformation to take into account , I just want to see the spatial oscillations of the rigid delta wing about its longitudinal axis as it enters the high alpha regimes at low Reynolds's number . Hope you are getting my point .
Thanks Again
