A STUDY OF FLOW FIELD AROUND FULL SHIP FORMS IN MANOEUVRING MOTION (2ND REPORT: HYDRODYNAMIC FORCES AND PRESSURE DISTRIBUTION ON SHIP'S HULL IN STEADY TURNING CONDITION)

In the previous report dealing with the oblique towing condition, the flow field around tow full ships with different aft hull forms were investigated by numerical computation and experiments. A comparison between the numerical computation and experiments was carried out for the same ships in steady turning condition. Detailed measurement of the hydrodynamic pressure on the whole hull surface was executed, and the longitudinal distribution of sectional lateral force was obtained by integrating the measured pressure along a contour of transverse section of the ship hull at various square stations. The measured pressure on the hull and longitudinal distribution of sectional lateral force were compared with numerical solutions of Navier-Stokes equation. The results are described in the paper. The comparison shows that agreement between numerical computation and experiments is fairly good. In particular, it should be noted that the difference in hydrodynamic lateral force and turning moment between two ships with different hull forms can be successfully predicted by numerical computation, and the difference in manoeuvrability of two ships can be definitely correlated to the difference in lateral force distribution caused by the difference in hull-form by means of numerical computation and experiments.
