CFD results obtained with PETScFEM (page 1)

The external cylinder (R=3) is fixed and the internal one (R=2) performs a periodic motion d=d0*sin(w*t), with d0=0.75, w=1.05. Viscosity of fluid is nu=1e-4. (Part I,Part II). In Part II of the video we show the movement of particles (tadpoles) and the transformation used. Warning: the mesh shown is not the actual mesh used in the computation. The mesh shown here is roughly 1:6 times coarser than the mesh used, and it is shown only in order to see the orthogonal transformation used. The transformation maps the eccentric circular annulus to a concentric one and is based in the composition of two inversions (conformal) and a final non-conformal (but orthogonal)
Large displacement formulation implemented in PETSc-FEM. This implementation is used in the Fluid Structure-Interaction problems. Download a recent paper on FSI) (More videos: part 2,part 3,part 4,part 5,)
