A Prediction Method for Three-Dimensional Boundary Layers on Ship Forms at Zero Froude Number

A method to predict the three-dimensional turbulent boundary layer on ship forms is introduced. The present differential method is in the scope of thin boundary layer theory and adopting the eddy-viscosity turbulence model. Two different numerical schemes are taken in this paper to handle the sign-changing cross-flows. The method is applied to predict the boundary layer development on real ship forms; SSPA Model 720(<TEX>$C_B$</TEX>=0.675) and HSVA Tanker Model(<TEX>$C_B$</TEX>=0.85). The results are qualitatively in good agreements with measurements except at the very stern. Therefore the method seems to be very promising if further developments are accomplished to handle the thick stern boundary layer effectively.
