The results of a number of model tests at the Versuchsanstalt fur Wasserbau und Schiffbau, West Berlin are presented. Most of the tests have been reported in greater detail in FDS Report 50/75. However, tests with a 25-m (scale ratio 11.2) model of a tanker have not been reported previously. Together with the results of tests with geosin models of scale ratio 1:55, 42 and 33 1/3, this allows conclusions to be drawn as to scale effects. It has been found that these are very small, both without a propeller and with a running propeller. The form and extent of flow separation are determined mainly by the local flow conditions ahead of and above the propeller and at the bilges. Changes in speed, propeller loading and small changes in draught have little effect.
