Simulation of free-surface flow using code FINFLO for KVLCC2 and KCS cases

Source: OAI

ABSTRACT Gothenburg 2010. A workshop on numeriacl ship hydrodynamics. Proceedings Volume II, 657-661 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. Gothenburg 2010. A workshop on numeriacl ship hydrodynamics. G2010, Göteborg 9 - 11 Dec. 2010
