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.
