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…
Modeling flying formations as flow-mediated matter
Christiana Mavroyiakoumou, Jiajie Wu, Leif Ristroph
Collective locomotion of swimming and flying animals is fascinating in terms of individual-level fluid mechanics and group-level structure and dynamics. Here we bridge and relate t…
Flow interactions and forward flight dynamics of tandem flapping wings
Fang Fang, Christiana Mavroyiakoumou, Leif Ristroph +1
We examine theoretically the flow interactions and forward flight dynamics of tandem or in-line flapping wings. Two wings are driven vertically with prescribed heaving-and-plunging…
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…
