Applied Math Seminar: modeling complex fluid structure interaction in sperm and ciliary motility.

Abstract: The motility of sperm flagella and cilia are based on a common axonemal structure. We describe a fluid-mechanical model for the ciliary and sperm axoneme. This fluid-mechanical model, based on the immersed boundary method, couples the internal force generation of dynein molecular motors through the passive elastic axonemal structure with the external fluid mechanics. We show an extension of our original model for Newtonian fluids to complex viscoelastic fluids in order to model mucus transport by cilia in the respiratory tract as well as sperm motility in reproduction. These immersed boundary models for sperm and ciliary motility in complex fluids explore continuum approaches such as Oldroyd-B as well as Lagrangian moving mesh methods.

Contact Co-organizers: Kim Vincent and Kathleen Ryan, Interior Design.
Various disciplines dealing with spatial relationships and reasoning will be examined. We will discuss what spatial reasoning is and how to improve students' spatial reasoning. The book, Learning to Think Spatially: GIS as a Support System in the K-12 Curriculum will be used. A read-only version may be found at www.nap.edu/catalog.php?record_id=11019
