Hello
I encountered a problem when I am trying to do some calculation with XFOIL. I did some measurements with an airfoil in a wind tunnel. And now, I would like to do some calculations with XFOIL using the same configurations as in the measurements. Since XFOIL gives CL CD directly, I think it is necessary to know the type of fluid (in order to use the right \rho). How can I check that? Or is it possible to change the fluid type to air? Maybe I am wrong...Please enlighten me. Thank you very much. |

Hi,
When you use XFoil, if defining a viscuous calculation, you have to set the Reynolds number and Mach of the simulation. That's the only way you define your fluid, and it should be enought. |

Thank you for your reply...
I still have some doubts...If the fluid type is only defined this way, how would XFOIL calculate CL CD? Since we need F/(0.5\rho U^2 S) to get CL CD, right? Or does it calculate those another way? Thank you |
