High Mesh Skewness on Cusp Trailing Edge
1 Attachment(s)
Hey everyone, I've been running a quasi-2D analysis on an airfoil in CFX and for some reason I keep getting minor fluctuations in lift, drag, and moment coefficients every time a run a simulation. I think its because of the high skewness in my mesh at the cusp trailing edge. I attached a photo of the inflation layers in that area. Any idea how I can go about fixing it?
Thanks a lot! |
Hi, this is an old thread. But if anyone is still interested to run a simulation on the NACA 0012, NACA 4415, FX 61-184 E420 and S1223 airfoil, please take a look at:
Numerical Investigation on the Pressure Drag of Some Low-Speed Airfoils for UAV Application. https://doi.org/10.37934/cfdl.13.2.2948 Unsteady 3-equation k omega intermittency SST was used. Good comparison with XFOIL and experimental data. Transition features also shown through cf and cp plots. Learn how I designed the mesh here: https://www.youtube.com/watch?v=qZRqBu9Ss2U |
hi jmcquaid
Check the following document. it is a very good resource for ansys meshing https://drahmednagib.com/CAD_2018/Le..._Meshing_2.pdf i hope it helps |
