| description | A new method for studying the interaction between an elastic object and a fluid has been developed. The fluid phase including solid interface is solved by our immersed solid method of body-force type. In the present study, the fluid-solid interaction force is incorporated into the finite-element method. This process is done by a superposition of the hydrodynamic force field with the solid internal force field. The inter-phase momentum exchange is implemented through the distributed force field shared by both Eulerian and moving Lagrangian references. In this paper, we demonstrate the recent results of our conservative momentum exchange algorithm for the fluid flow bounded by elastic walls. Examples include two-dimensional flows through a gap between modeled vocal cords, and some three-dimensional demonstrations. |
