Abstract
This paper presents to case study the method design of 3-blade type ship propeller. cavitation flow is investigated around ship propellers experimentally. Testing of different types new model propellers and local type propellers are performed in this study. A 3-blades, skew angle 18 degree, developed area 55 and comparison which local type propeller commonly used by Thai fishermen. A practical design method was achieved by combining a vortex lattice lifting method and lifting surface method. The optimum circulation distribution yielding the maximum lift-to-torque ratio was computed for given thrust and chord lengths along the radius of the propeller by dividing the blade into a number of panels extending from hub to tip. The radial distribution of bound circulation could be computed by a set of constant-strength vortex elements. The cavitation phenomenon of new design appeared to be less than local type
