Abstract

This paper is presented a combined method to design of the twin-waterjet propulsion system for high-speed craft (HSC). First, a practical approach employed to obtain the main data of the geometry of waterjet system. Thrust of the system is calculated by the momentum theory. Next, RANS solver is performed with the realizable k-ε turbulence model. The numerical results of the pressure distribution coefficient, thrust coefficient and the flow field inside the duct are presented and discussed.

Keywords:
twin-waterjet practical and numerical method pressure and thrust coefficients
