Abstract
RANS solver FINFLO is used to simulate the turbulent free-surface flow around two ship hulls. FINFLO solves the three-dimensional RANS equations by the method of artificial compressibility. A non-linear free-surface boundary condition is implemented in the code for the treatment of hull flows. Calculations of the KRISO tanker (KVLCC2 model) and the KRISO container ship (KCS) are presented. The k-? SST turbulence model has been utilized in the computations for both ships and submitted for the comparative study. Measurements from POSTECH and MOERI are available for validation purposes. They include free-surface waves, total resistance and velocities at different locations. Good correlation of resistance coefficients with measurements is obtained for both ships. The predictions of wave profiles are especially good for both cases near the hull.

| Other | The Gothenburg 2010 Workshop on Numerical Ship Hydrodynamics was held in Gothenburg on 8-10 December, 2010. It was the sixth in a series of workshops held alternatively in Gothenburg and Tokyo since 1980. The purpose has been to assess the performance of contemporary CFD codes used in hydrodynamics. In the present workshop three hulls of different types were used and 18 test cases using these hulls were specified by the organizers. 33 groups carried out computations for one or more cases and reported the results to the organizers who compiled the results. |
