# Elizabeth Bouzarth : Using Regularized Stokeslets to Model Immersed Biological Fibers

The behavior of inextensible fibers immersed in a fluid is of interest in a variety of applications ranging from polymer suspensions to actin filament transport. In these cases, the dynamics of an immersed fiber can play a large role in the observed macroscale fluid dynamics. The method of regularized Stokeslets provides a way to calculate fluid velocities in the Stokes fluid flow regime due to a collection of regularized point-forces without computing fluid velocities on an underlying grid. In this discussion, the method of Regularized Stokeslets will be used to model the dynamics of an inextensible flexible fiber immersed in a two-dimensional cellular background flow in comparison with results found in the experimental and mathematical literature. Studying this scenario with regularized Stokeslets provides insight into the documented stretch-coil transition and macroscale random walk behavior supported by mathematical models and experimental results.
