Numerical analysis of incompressible viscous flows interacting with flexible structures
In this paper, an efficient way to treat the interaction between an incompressible viscousfluid and an elastic body in a fully coupled arbitrary Lagrangian-Eulerian formulation is presented.The constitutive relations for both uid and exible body are unified into the same form, and exiblebody part is imagined as a special uid which can have the same form of governing equations as theNavier-Stokes equations for uid ows. Numerical example of an incompressible viscous channel owaround an elastic plate attached on the solid channel wall which results in self-induced oscillations of the structure is provided to show the efficiency of the presented method for detailed simulations ofincompressible viscous ows interacting with exible structures.
