Abstract
The present research explores the stern flow hydrodynamics around a maneuvering ship. Utilizing Computational Fluid Dynamics (CFD) techniques, several flow scenarios including different drift angles and propulsion configurations are modeled for the benchmark ship KRISO Very Large Crude Carrier 2 (KVLCC2). The analysis depicts all vortical structures that appear in the propeller operating area, explaining their formation and evolution. Also, the mutual interactions between the turbulent flow and the propulsion unit are observed and examined. The detailed outcome is intended to provide valuable insights for both new ship design and retrofits, aiming to advance new and sustainable engineering practices.
