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.

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 components can be decomposed into a Fourier expansion series of time harmonic components....

Conference Proceeding
Amini, S., Elmazuzi, R., & Nixon, S. P. (2004). Multiwavelet Collocation Boundary Element Solution of Laplace's Equation.

In this paper we present the result of a preliminary investigation into the collocation method, based on multiwavelet approximation, for boundary integral equations with analytically standard kernels. We apply the method to the boundary integral solu... Read More about Multiwavelet Collocation Boundary Element Solution of Laplace's Equation.
