Immersed Boundary Methods for Rigid and Deformable Particles in Viscoelastic flows — •Eric Shaqfeh — Department of Chemical Engineering, Stanford University

The immersed boundary method will be used with a finite volume fluid solver to develop a unique tool to examine the properties of a viscoelastic suspension of particles. The tool will employ unstructured grids and is massively parallel, thus allowing very complex geometries to be simulated. Since the internal stress of the particles is handled using a finite element solver, nearly arbitrary stress-strain relationships for the particles can be handled and their shape can deform continuously. A number of interesting physical problems will be examined with the code including 1) Sedimentation of particles in orthogonal shear and 2) the rheology of particulate suspensions in a viscoelastic fluid under shear.
