Vorticity Contour and Pressure Coefficient Anomalies

    • vatakere

      I am having issues simulating an airfoil and its Cp vs x/c curve. It's supposed to have an Reynolds number of 1.975e5, but the flow does not appear to be in that regime. The pressure coefficent curve does not matach with the experimental data and has some spikes in it while the voritcity magnitude contour has pockets of slightly higher velocity at the leading edge. The mesh is also refined to its optimal state (yplus around 1). Do you know what is causing these issues?

      You will need to check the boundary conditions and the setup. Here is a tutorial that would be helpful : Flow over an Airfoil - ANSYS Innovation Courses
