A minimal wake-vortex model explains formation flight of flapping birds
Olivia Pomerenk, Kenneth S. Breuer
Collective patterns of motion emerge across biological taxa: insects swarm, fish school, and birds flock. In particular, many large migratory bird species form distinctly ordered V…

Quasi-steady aerodynamics predicts the dynamics of flapping locomotion
Olivia Pomerenk, Leif Ristroph
The propulsion of a flapping wing or foil is emblematic of bird flight and fish swimming. Previous studies have identified hallmarks of the propulsive dynamics that have been attri…

Aerodynamic equilibria and flight stability of plates at intermediate Reynolds numbers
Olivia Pomerenk, Leif Ristroph
The passive flight of a thin wing or plate is an archetypal problem in flow-structure interactions at intermediate Reynolds numbers. This seemingly simple aerodynamic system displa…
