2D NACA0015 aerodynamic coefficients computimg
Hi,
I'm fresh in Fluent. I have an easy question here. I want to get the aerodynamic coefficients of NACA0015 airfoil. But the results do not match with the data of others. So I need some help about the set in Fluent, such as choose Laminar or Spalart-Allmaras?steady or unsteady? Thanks in advance! |
Hello,
normally, I'd say this is a steady case. You have to decide whether this is laminar or turbulent by calculating the Re-number... Also be sure that your calculation area (especially behind the airfoil) is long enough and the wall y+ is acceptable. Furthermore, cell refinement at the gradients (of pressure e.g.) should be set up. There's a tutorial at https://confluence.cornell.edu/displ...+Specification check it out! |
