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…
Enhancing heat transfer in a channel with unsteady flow perturbations
Silas Alben, Shivani Prabala, Mitchell Godek
We compute unsteady perturbations that optimally increase the heat transfer (Nu) of optimal steady unidirectional channel flows, for a given average rate of power consumption Pe$^2…
Dynamics of flags over wide ranges of mass and bending stiffness
Silas Alben
There have been many studies of the instability of a flexible plate or flag to flapping motions, and of large-amplitude flapping. Here we use inviscid simulations and a linearized…
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…
Collective locomotion of two-dimensional lattices of flapping plates
Silas Alben
We study the propulsive properties of rectangular and rhombic lattices of flapping plates at O(10--100) Reynolds numbers in incompressible flow. We vary five parameters: flapping a…
