A Fortran compiler can be built from sources or installed from Homebrew. Xfoil is implemented in Fortran and C, so we’ll need a C and Fortran compiler. In order to be able to build and run Xfoil on OS X you will need an X server like XQuartz. For OS X, well, it is a bit more complicated to build the code from sources.Ī typical Xfoil result is presented in the next figure: If you are a Linux user building Xfoil from sources is straightforward. The author, Mark Drela, provides a Windows binary on Xfoil’s web page. Xfoil uses a potential flow solver coupled with a Boundary Layer solver to calculate the flow field around an airfoil. Xfoil is an open source interactive program for the design and analysis of subsonic isolated airfoils. In the former case a typical analysis can run from a few minutes to a few hours on a modern PC. Compare this with a full CFD approach that uses the Navier-Stokes equations for the laminar part of the flow and the Reynolds Averaged Navier-Stokes equations for the turbulent part of the flow. On a modern computer this analysis will usually take less than a minute. The classical approach to calculate the performance of an airfoil is to use a coupled inviscid/viscous flow solver. If you are into airfoil analysis as an amateur or as a professional you will need a quick way to estimate the aerodynamic characteristics (lift, drag and momentum coefficients) of a given airfoil.
