Abstract
- This work presents a strongly-coupled fluid–structure interaction (FSI) formulation for compressible flows that is developed based on an augmented Lagrangian approach. The method is suitable for handling problems that involve nonmatching fluid–structure interface discretizations. In this work, the fluid is modeled using a stabilized finite element method for the Navier–Stokes equations of compressible flows and is coupled to the structure, which is formulated using isogeometric Kirchhoff–Love shells. The strongly-coupled system is solved using a block-iterative approach. The proposed method is validated using two compressible flow benchmark problems to assess the accuracy of the developed formulation. [ABSTRACT FROM AUTHOR]
