Consequently the forces acting on the walls of\r\nthe channel due to the fluid pressure are also large. Due to these forces\r\nthere are displacement fields set up in the solid substrate containing\r\nthe channels. If the movement of the substrate is constrained at some\r\npoints, then stress fields are established in the substrate. On the other\r\nhand, if the deformation of the channel shape is sufficiently large\r\nthen its effect on the fluid flow is important to be calculated. Such\r\ncoupled fluid-solid systems form a class of problems known as fluidstructure\r\ninteractions. In the present work a co-located finite volume\r\ndiscretization procedure on unstructured meshes is described for\r\nsolving fluid-structure interaction type of problems. A linear elastic\r\nsolid is assumed for which the effect of the channel deformation\r\non the flow is neglected. Thus the governing equations for the\r\nfluid and the solid are decoupled and are solved separately. The\r\nprocedure is validated by solving two benchmark problems, one from\r\nfluid mechanics and another from solid mechanics. A fluid-structure\r\ninteraction problem of flow through a U-shaped channel embedded\r\nin a plate is solved.","references":null,"publisher":"World Academy of Science, Engineering and Technology","index":"Open Science Index 55, 2011"}
