Quasi-2D Mesh Requirements
Hi everyone,
I'm working with a NACA profile to simulate the flow over an airfoil. It can be done with a two-dimensional case, but the turbulence models didn't work so well for that, so I decided to run the case with a three-dimensional geometry, where the width is represented by Z-axis. My entire domain is about 1 meter length. I extruded the sketch only for 0.001 m. Even so, the results are not good enough. I want know if the thickness of my geometry is important in this case. I set symmetry plane conditions for the perpendicular planes to Z-axis, so wall proximity wouldn't affect the flow. There's only two nodes in the Z-direction, that is, there's only two nodes in the mesh on the left, right, top and bottom sides of my template. Is that a problem? Do I need more nodes? Is this a limiting factor for my template? Thks. Best regards. |
