Appendage effect evaluation on the forward resistance reduction
This paper shows experimental and numerical results of three types of appendages on the forward resistance reduction of displacement and semidisplacement hulls. The forward resistance results were obtained using Computational Fluid Dynamics and towing tank tests. The evaluated appendages are stern flaps and interceptors for displacement hulls and sprayrails for a semiplaning hull. The experiments are independent from each other and no research was undertaken to include the combined effect of appendages on a single hull. The predicted reduction in forward resistance in all three tested devices, is around 5-10%, showing potential for fuel saving through the evaluation of hydrodynamic effects of energy saving appendages.
