A Review of Computational Modeling of Fluid-Immersed Flexible Filaments

Hydrodynamics of slender flexible filaments plays an important role in biology, human physiology, locomotion of organisms, as well as biomedical devices. It is, therefore, important to utilize efficient and accurate numerical models for capturing fluid–structure interaction involving flexible slender structures for numerically simulating such biological systems. In this review article, several computational techniques for evolving the hydrodynamics of slender flexible filaments have been discussed. Special emphasis has been placed on continuous forcing immersed boundary method and slender body theory due to their utility in efficient simulation of thin rod-like filaments.
