Complex systems, such as the flow around a wind turbine, are often characterized by coupled physics, e.g., fluid-structure interaction (FSI). In an industrial setting, FSI problems are typically solved via the employing of partitioned coupled high-fidelity solvers. The high-fidelity solvers that are often denoted full-order models (FOMs), are typically too computationally costly to be used for real-time control and parametrized problems. We therefore explore the possibility to use coupling of separately-constructed projection-based reduced order models (ROMs). The proposed strategy starts by sampling the CFD solver over a set of valid points and constructs a hybrid ROM as described in [1], that is, using the proper orthogonal decomposition with Galerkin projection and interpolation schemes for turbulent contributions. The offline phase employs OpenFOAM’s finite-volume solvers, while geometric consistency is ensured via an imposed mesh point transformation and pull-back operations [2]. Similarly, a parametrized elasticity solver is sampled, and a ROM is constructed. In the online phase, a staggered coupling is enforced where the fluid ROM is solved initially, and its output is followed by the solution of the kinematics for the solid. In the numerical examples, the accuracy of the proposed ROM methodology is compared with the corresponding FOM.
