Abstract:

An experimental program was conducted at the David W. Taylor Naval Ship RD Center DTNSRDC to aid in the identification and resolution of the hull vibration problem experienced by the Auxiliary Oiler AO 177 and to validate possible remedies. The formulated program included evaluations with three tunnel-fin configurations fitted to the stern of the model. The experiments involved visual flow observations, propulsion experiments and wake surveys experiments. This report deals exclusively with the observations of the flow variations for three different tunnel-fin configurations. The propulsion experiments and wake survey experiments will be published in separate reports. An improved flow pattern was observed with the tunnel-fin designed as configuration number one. Author
