报告摘要：

Motivated by fluid-structure-interaction (FSI) phenomena in life sciences (e.g., erythrocytes moving in flowing blood), we consider a simple FSI model problem --- interaction of an elastic plate (fixed at the midline) with a non-Newtonian fluid flow in three dimensions. The constitutive equation of the non-Newtonian flow is modelled by power-law functions. The fluid flow is modelled by the lattice Boltzmann equations. The deformable structure and the fluid-structure interaction are handled by the immersed boundary (IB) method. Drag of the plate is computed, drag scaling is studied, and effects of several dimensionless parameters including exponent of the power laws, Reynolds number, and plate bending modulus on drag and its scaling are investigated. An interactive implementation of the algorithm on two GPUs are also presented.

报告人简介：

Dr. Luoding Zhu got his PhD in applied math in 2001 from Courant Institute of Mathematical Sciences, New York University working with Charles S Peskin. He did a postdoc at University of California Santa Barbara with Linda Petzold at Computer Science 2001-2004. He Joined the Department of Mathematical Sciences of Indiana University-Purdue University Indianapolis (IUPUI) in 2004 as an Assistant Professor and currently works at the same institution as an Associate Professor. His main research interest includes applied numerical methods for Fluid-Structure-Interaction, mathematical modeling and computer simulation of blood flows and cell-fluid-extracellular-matrix interaction.
