INTERACTION OF OSCILLATING FILAMENTS - A COMPUTATIONAL STUDY

The immersed boundary technique is used to model the interaction of swimming filaments in a viscous, incompressible fluid. Fluid quantities are represented on a grid, and the immersed filaments are each represented by a discrete collection of moving points. The effects of phase differences and proximity of the filaments on energy dissipation and swimming speeds are studied. The computed results are compared with previous asymptotic analysis. Furthermore, we present case studies which exhibit phase-(un)locking phenomena undetectable using previous asymptotic analysis. © 1990.
