Sažetak
The study presented in this paper is a part of the project whose goal is to build a selfcontained Finite Volume Method (FVM) Fluid-Structure Interaction (FSI) solver to simulate dynamic interaction between an incompressible Newtonian fluid and an elastic solid with the assumption of large structural deformation. The structural component of the FSI solver is described and validated. It applies the second-order cell-centred finite volume method for spatial discretisation of the linear momentum conservation law in the updated Lagrangian formulation. Temporal discretisation is performed by using a fully implicit second-order accurate three-timelevel scheme and equations are solved by using a segregated iterative algorithm. The solver is validated on the vibration of a three-dimensional (3-D) cantilevered elastic beam and used to simulate the dynamic response of an axial turbine blade. It is shown that an accurate and stable numerical solution can be obtained over a long time period of transient simulation.
