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…
Tesla's fluidic diode and the electronic-hydraulic analogy
Quynh M. Nguyen, Dean Huang, Evan Zauderer +3
Reasoning by analogy is powerful in physics for students and researchers alike, a case in point being electronics and hydraulics as analogous studies of electric currents and fluid…
Flow rectification in loopy network models of bird lungs
Quynh M. Nguyen, Anand U. Oza, Joanna Abouezzi +4
We demonstrate flow rectification, valveless pumping or AC-to-DC conversion in macroscale fluidic networks with loops. Inspired by the unique anatomy of bird lungs and the phenomen…
