Implementation and Evaluation of Fluid-Structure-Interaction for Propellers

Abstract

The thesis aims to implement and evaluate a one-way Fluid-structure coupling for propellers. In this context, the focus is to study the influence of scaling effects as most hydrodynamic evaluations of propeller performances are carried out at model scale and structural analysis at full scale. To understand the differences, all calculations are performed in both scales. Hydrodynamic influences are compared between the scales and structural analysis analyses are compared between scaled model scale vs. full scale. The thesis, also aims to propose a reduced method of evaluating hydrodynamic performances, as this part of the evaluation is the most time consuming.. The reduced evaluation shows promising results and faster convergence with lower computational cost.
