Abstract
This document describes different strategies to model 2D movable control surfaces. The system to be modeled corresponds to a NACA0012 airfoil where a portion of the tail is used as a flap, under subsonic flow. The flap can be rotated from -30 to 30 degrees and a gap between the movable surface and the rest of the airfoil can be included. For the modeling of the control surface movement, mesh deformation using Radial Basis Functions and the chimera technique are used to obtain meshes for the different angles. The strategies are compared in terms of the results for the drag, lift and pitching moment coefficients.
