Propellers are essential in vessels as they convert engine energy into thrust, influencing their operation and efficiency. An incorrect selection can lead to issues with speed, maneuverability, and high fuel consumption. It is crucial to develop methodologies using CFD tools to make preliminary design estimations and ensure efficiency and safety. This work proposes a two-stage optimization approach: first, using a multivariable trust-region algorithm, followed by the Nelder-Mead method combined with constraints applied via Newton-Raphson in OpenFoam. Geometric variations in B-series propellers are studied, yielding performance improvements under specific operational conditions.
