|Title:||Inertial swimming as a singular perturbation|
|Seminar:||Applied Analysis Seminar|
|Speaker:||Steve Childress, Courant, NYU|
|We revisit the classic problem of swimming of a sheet studied by G.I. Taylor in Stokes flow. At finite and large
Reynold number Taylor's result is modified. The known results are reexamined for large Reynolds number using boundary-layer theory, and the nature of the expansions is clarified for wave-like motions of the sheet.
We apply this approach to recoil swimming, a mechanism of locomotion that is known to work in a perfect fluid,
thus extending the theory to a slightly viscous fluid.|
