Summary on Grant Application Form |

Water-jets have many advantages over conventional propellers for high speed ship propulsion including elimination of drag, improved manoeuvrability as well as a reduction in fuel consumption in high speed cruise. They, therefore, provide the best means of propulsing the new generation of fast ferries that are increasingly replacing the traditional passenger and car ferries.The proposed study will look into three main areas of water-jet hydrodynamics, where better understanding and/or design should lead to substantial improvement in performance. Firstly, the effects of water-jet/hull interactions will be investigated both numerically and experimentally, with specific reference to prediction of torque and thrust deduction factor. Further studies will be undertaken to investigate the effect of duct shapes, computed by inverse design methods currently under development at UCL, on the duct pressure recovery and exit flow distribution. In addition, the pump flow field is computationally modelled under unsteady conditions, in order to investigate the effect of different water-jet inlet conditions on the inception of cavitation and noise in the pump impeller.
