Performance of high speed planing hull with stern interceptor in calm water and waves

Using a numerical method, the present study examines the performance of planing hulls in head waves and calm water with and without interceptors.Because it is costly and challenging to measure in experiments, the hydrodynamics of planing hulls using computational models predicts both drag and the hull's free surface wave.In the present study, flow is simulated using a commercial Reynolds-averaged Navier-Stokes equation (RANSE)-based tool.The results are compared with tests conducted for the planing hull with and without an interceptor in calm water at the towing tank, Department of Ocean Engineering, IIT Madras, Chennai, in order to validate the numerical model.For further research on regular head waves for planing hulls with and without interceptors, the same computational simulations are used.The study finds that a hull equipped with an interceptor reduces resistance and free surface wave height in both calm and regular head waves.
