Fluent Flapping Wing Simulation - Vorticity Contours

A small part of my BSc. thesis in mechanical engineering. This simulation captures the non-stationary lift-enhancing mechanisms responsible for insect flight (leading edge vortex, wake capture, wing-wake interactions) Flapping wing aerodynamics is currently an area of active research and is of special interest in the development of Micro and Nano Air Vehicles, such as the Nano Hummingbird ( The proyect involved a parametric study (angle of attack, rotation delay, flapping mode) in search for the best aerodynamic performance. This video shows 2 among 30 different cases. Chord: 7mm Frecuency: 60Hz Flapping Amplitude: Mesh: elements The movement is achived using a UDF and dynamic meshing (remeshing smoothing). I’m glad to answer any questions :)
