The problem studied was the non-reciprocal cyclic swimming motion of three spheres linked with axially aligned retractable arms in Stokes flow. The arms are assumed to be able to retract at a steady speed to half their length, and then at a later tim...

Consider uniform flow past an oscillating body generating a time-periodic motion in an exterior domain, modelled by a numerical fluid dynamics solver in the near field around the body. A far-field formulation, based on the Oseen equations, is present... Read More about A coupled far-field formulation for time-periodic numerical problems in fluid dynamics.

Oscillatory oseenlets (2011)
Thesis
Elmazuzi, R. Oscillatory oseenlets. (Thesis). University of Salford

Consider uniform flow past an oscillating body. Assume that the resulting far-field flow consists of both steady and time periodic components. The time periodic component can be decomposed into a Fourier expansion series of time harmonic terms. The... Read More about Oscillatory oseenlets.
