Pressure coefficient in StarCCM

AmGS · June 6, 2018, 05:11

Good morning,

I'm currently trying to analyze a wing with the NACA 0015 to get the pressure coefficient in several sections of the wing.

However, the Cp results show fluctuations, why does this happen?
Attached an image of the mesh and the graph of Cp

Thank you very much

Best regards

Is this simulation - unsteady or steady case?

Steady case

try to refine the region very near the airfoil by giving more no of prism layers..make a volumetric control region surrounding the airfoil using volumetric control so that it is finely meshed near the airfoil surface to get better results..
