Abstract
Distance fields finds a lot of applications recently
in computational geometry. We propose an algorithm to extract the mean camber
line of an airfoil using distance fields. This method does not require
computing any geometric approximations in- side the airfoil geometry. It also
does not need the airfoil coordinates to be evenly distributed on the top and
bottom. All the computations are done on a simple Cartesian mesh and can be
easily coupled with any existing computational fluid dynamics codes. We show
the efficiency of the algorithm on a variety of airfoil geometries. We demonstrate
the robustness and exibility of the algorithm for a wide range of airfoil geometries.
