FLOW FIELD MEASUREMENT AROUND SHIP HULL AT INCIDENCE

The flow field around a ship hull at incidence was measured using a five-hole Pitot tube operated by an automatic flow measuring system. The system developed for measurements in a circulating water channel is described first, and consisted of a sensor-controlling system, a type of robot manipulator, and a data aquisition system. Flow velocity vectors around ship models were automatically measured using several microcomputers. The results of measurements around a ship hull at incidence are presented for the whole of the back side region from fore to aft peak. The vortex separated at the fore part travels with the outer potential flow. The path of the vortex is therefore different from that for a full form ship such as a tanker model.
