Effect of Three-Dimensional Geometry on Harmonic Gust–Airfoil Interaction

What is it about?

It is common practice in many engineering applications to use simplified 2D modelling to estimate the loads acting on wings and rotor blades as a result of turbulence, or "gusts". However, this is not appropriate on geometries that are strongly three-dimensional. This study explores the limits of applicability of 2D modelling on 3D geometries, and demonstrates some of the fundamental differences between unsteady flow response in 2D and 3D.
