Abstract

In this paper, we present a study of fully coupled 2D+ FSI model of a deformable airfoil supported at a few points by translational springs. These translational springs represent the third dimension (wing span) structural rigidities (bending and torsion). This 2D+ FSI model is more sophisticated than traditional two-dimensional (2D) model with rigid airfoil and is a simplified version of full fledged three-dimensional (3D) FSI models. The results derived from explicit and implicit immersed methods are compared with those of FSI modeling with adaptive meshing techniques. Although the fluid flow setting is that of a wind tunnel, it is anticipated that with this 2D+ model and proper radiation boundary conditions, it is possible and computational feasible to explore parametric and phase spaces for various design options for external flow environment.
