Accurate numerical prediction of the flow characteristics near a marine propeller and in its wake is essential when assessing the underwater acoustic footprint, as the flow field especially in the wake can be very complex and highly transient. Advanced numerical simulation methods provide valuable insight to the flow features in the propeller wake. High-fidelity turbulence modelling approaches such as DDES further enhance the resolution of the flow details. The cover shows the flow field in the propeller wake, visualized by vortical structures. Several features of the flow can be clearly identified, including the characteristic propeller tip and hub vortices as well as phenomena related to unsteady vortex shedding. View this paper.
