... influencing the optimum. The results indicate that a 3-4 % smaller diameter is optimal in behind conditions in relation to open water conditions at the same scale factor. The reason is that smaller, higher loaded propellers perform better together with a rudder system. This requires that the gain...

... In spite of recent CFD progress, simple methods for the estimation of the propeller hydrodynamic loads through stationary non-uniform wake in relation to cargo ship shafting alignment and vibration calculations are still demanded. The paper concerns with the propeller load calculation results...

... of the SSPA Cavitation Tunnel. By varying the water speed over a wide range, full scale, as well as typical model test Reynolds' numbers, were covered. Also the gas content of the water was varied. The results confirm the relation between Reynolds' number and inception found in the literature, provided...
