Numerical simulation of fluid-particle interactions (1995) [1 citations — 1 self]
Abstract:
We perform numerical simulations of several 3D fluid-particle interaction problems. We simulate the sedimentation in a liquid filled tube of multiple spheres ranging in number from two to five. The NavierStokes equations for incompressible flow are solved using the stabilized space-time finite element method. This method gives us the flexibility to move the mesh to accommodate the motion of the spheres. Along with the ability to move the mesh comes the emphasis on mesh moving algorithms. Here, we demonstrate the methods we developed to move the mesh in 3D applications. These methods include explicitly defined rules, moving the mesh according to a governing equation, and remeshing as needed. 1.
