Abstract

The flow around a ship at yaw angles beyond those
encountered during manoeuvres has not been the
subject of much research reported in the literature.
These conditions are particularly important for an
escort tug, since it uses large yaw angles to generate
hydrodynamic forces that are used to control a ship
(normally a tanker) in the event of an emergency.
This paper presents CFD predictions for the flow
around an escort tug at a yaw angle of 45 degrees and
compares them to PIV measurements of the flow
patterns. The CFD code predicts the essential
features measured within the flow, such as the
separation of the flow from the upstream bilge, and
the formation of a large vortex generated by the low
aspect ratio fin. The predicted vectors were compared
with the measured ones using a numerical technique,
and the agreements were found, on average, to be
within 10%. This level of agreement was within the
estimated uncertainty of the PIV system used for the
experiments.
