Validation of viscous flow and wake field predictions for ships at full scale

In this paper full-scale wake field validations for a number of ships are presented and discussed. It will be shown that accurate viscous-flow computations are possible at full scale, which show good correlation with experimental data measured during sea trials with shipmounted LDV systems. It will be shown that the effect of turbulence closures on the longitudinal vorticity, well-known at model scale, occurs at full scale as well. Of the turbulence closures tested, those that perform well at model scale are also found to perform well at full scale.
