Descripción
This paper describes the theoretical development and implementation issues of a far ?eld induced drag extraction tool based on the Maskell integral. Far ?eld methods provide an alternative to classical near ?eld approach, o ering the possibility of decompose drag contributions based on their physical source and improves prediction accuracy on coarse meshes. Instead of classical triangulation of intersection nodes contained in the cutting plane, a more regular adaptive mesh is implemented in order to improve ow reconstruction smoothness and accuracy. Both meshes results are compared and the in uence of generation parameters of the bidimensional adaptive mesh is discussed. Numerical di usion plays a major role in vortex decay, and because of that phenomena, a correction factor is needed in order to back as much as possible the cutting plane without loosing precision. Finally, Onera M6 tests are conducted, showing acceptable precision in drag prediction until seven or more chords downstream.
