A STUDY OF MACHINERY AFT CONDENSER SCOOP INSTALLATION IN MANEUVERING
The turning response of the condenser circulation system in a machinery aft installation was studied using computer simulations with data from wind tunnel tests of a model scoop systems installed in the stern of a 2.5 m tanker double model. These results agree qualitatively with the HAMPTON MARU scoop performance measurements in which a rise in the system's pressure was observed shortly after turning. The role the flow into the inlet plays in this pressure rise is described by the bow, side, and breakdown regions defined by the drift angle and derived from the ship's L/B ratio. Improvement of the inlet scoop performance was obtained by fitting a boundary layer fence. The interaction of the outlet scoop jet with the stern flow was visualized. The calculated flow pattern is compared to the flow around the stern of the double model at various drift angles.
