Abstract
A ship stern turbulent flow field of a double model (Series 60, C_B=0.6) was measured by triple-sensor hot wire system in the wind tunnel. The mean velocities and turbulent quantities were analyzed from the time history data of the fluctuated velocities, and detailed stern flow database was obtained. CFD calculations of RANS equation around the ship hull were carried out using k-ε turbulence model and tuned k-ε turbulence model. The results of computation were compared with measured velocities and Reynolds stresses distributions. The long period phenomena of the stern flow field at the Propeller plane were analyzed using the data of another set of triple-sensor hot wire system fixed in the flow field. The period of the motion of a longitudinal vortices in the model ship stern flow field was specified.
