Numerical investigation of lift enhancement in flapping hover flight
TL;DR: In this paper, an idealized set of kinematics for a NACA0012 airfoil consisting of sequential translations and rotations is considered for this purpose, such that the Cl response can be demarcated into translational and rotational parts, which facilitates comparison of forces attributed to translation and rotation.
