Summary

 
Object and purpose of research. This paper is intended to validate the set of CFD technologies for viscous fluid (digital basin) by means of the case study (investigation of KCS container ship model parameters).
Subject matter and methods.Local and integral hydrodynamic parameters of the container ship are investigated by means of CFD tools. Viscous flow parameters are obtained through control-volume solution of unsteady Reynolds equations, closed by bi-parametric semi-empirical turbulence model. Numerical simulation technologies are validated by extensive test data obtained by various test tanks.
Main results. Validation of the CFD tool set by means of the flow studies of KSC container ship and her propeller (calculation of towing resistance, trim & draft parameters, propeller performance curves, nominal wake field, hull resistance and trim & draft parameters in head waves, and also numerical simulation of self-propulsion tests) and by comparison of these data versus experimental results has confirmed high accuracy of modern calculation methods.
Conclusion. KSRC experience of numerical studies shows that the scope of tasks handled by numerical simulation is steadily becoming wider and wider. Applications of CFD methods in marine hydrodynamics enhances the potential of conventional test facilities in the studies on specifics of certain physical processes. Here, analysis of local flow peculiarities and their time history, as well as accuracy of full-scale predictions for ship under design, become very important.
