Partitioned simulation of the fluid‐structure interaction of flexible marine propellers in unsteady flow conditions

Abstract

Regarding new propeller materials and designs, vibrations and large deformations are becoming increasingly relevant. Therefore, simulation methods need to be developed which take into account the interaction of fluid and structure while retaining a computational effort suitable for the design stage. In the approach presented here, the fluid mechanical subproblem is solved by means of the software panMARE, which is based on the potential theory. The structural-mechanical subproblem is engaged using different structural solvers as well as modelling approaches. Information exchange between the subproblems is managed by the software comana.
