Flapping strategies for flying formations
Javier Chico-Vázquez, Christiana Mavroyiakoumou
Long arrays of identical, self-propelling flapping flyers are inherently unstable and thus unlikely to exist without active control mechanisms. One approach to enable long in-line…
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…
Order and Chaos in Systems of Coaxial Vortex Pairs
Christiana Mavroyiakoumou, Wenzheng Shi
Systems of coaxial vortex pairs in an inviscid flow give rise to complex dynamics, with motions ranging from ordered to chaotic. This complexity arises due to the problem's high no…
Sail dynamics during tacking maneuvers
Christiana Mavroyiakoumou, Silas Alben
We study the dynamics of sail membranes during a tacking maneuver, when the sail angle of attack is reversed in order to sail upwind. In successful tacking the sail flips to the mi…
Spanwise variations in membrane flutter dynamics
Christiana Mavroyiakoumou, Silas Alben
We study the large-amplitude flutter of rectangular membranes in 3-D inviscid flows. The membranes' deformations vary significantly in both the chordwise and spanwise directions. M…
Membrane flutter in three-dimensional inviscid flow
Christiana Mavroyiakoumou, Silas Alben
We develop a model and numerical method to study the large-amplitude flutter of rectangular membranes (of zero bending rigidity) that shed a trailing vortex-sheet wake in a three-d…
Dynamics of tethered membranes in inviscid flow
Christiana Mavroyiakoumou, Silas Alben
We investigate the dynamics of membranes that are held by freely-rotating tethers in fluid flows. The tethered boundary condition allows periodic and chaotic oscillatory motions fo…
Eigenmode analysis of membrane stability in inviscid flow
Christiana Mavroyiakoumou, Silas Alben
We study the instability of a thin membrane (of zero bending rigidity) to out-of-plane deflections, when the membrane is immersed in an inviscid fluid flow and sheds a trailing vor…
Large-amplitude membrane flutter in inviscid flow
Christiana Mavroyiakoumou, Silas Alben
We study the large-amplitude flutter of membranes (of zero bending rigidity) with vortex-sheet wakes in 2D inviscid fluid flows. We apply small initial deflections and track their…
The QRD and SVD of matrices over a real algebra
Paul Ginzberg, Christiana Mavroyiakoumou
Recent work in the field of signal processing has shown that the singular value decomposition of a matrix with entries in certain real algebras can be a powerful tool. In this arti…
