Fluid-rigid body interaction using a modified combined interface boundary condition method
In this paper,a new formulation for the combined interface boundary condition (CIBC) method is developed to cope with the problem of fluid-rigid body interaction.An arbitrary Lagrangian-Eulerian finite element method is used to analyze fluid-structure interaction (FSI).The characteristic-based split (CBS) scheme is employed to solve incompressible Navier-Stokes equations while the equation for rigid-body dynamics is solved by Newmark-β method.A numerical technique called moving submesh approach is performed for the mesh deformation.For respecting geometric conservation law,a mass source term is implanted into the CBS scheme on the moving mesh.Several numerical examples are tested to validate the proposed methodology for fluid-rigid body interaction.The obtained results are in agreement with the existing data and some famous features of flow phenomena have been detected successfully.
