Abstract : Numerical investigations is made into complex three-dimensional boundary layers around ship hull forms. At first, simple model of natural transition for boundary layers on ship fore-body surface is presented. Transitional boundary layer from laminar to turbulent calculated by using this model agreed very well with experimental results. Investigation is carried out about influence of the change of laminar boundary layer region and Reynolds number on the flow field around ship forebody. The results shows that unstable flow pattern at bilge part is varied drastically due to above influence at comparatively low Reynolds number since turbulence intensity is smaller than that at high Reynolds number.
