Summary:

The determination of ship’s resistance which is fundamental subject of ship

hydrodynamic is very important because of it is influence of ship main engine selection.

Computational fluid dynamic methods are carried out increasingly and are inserted into

design process in new ship building industry like other industrial areas.

At this study, ship resistance is calculated with computational fluid dynamic method

and each steps of computational fluid dynamic are explained comprehensively. In this

regard, firstly informations about equations of motions and control volume finite element

method are given. Turbulent fluid’s solution which is one the most important subject of

computational fluid dynamic is emphasized and k −ε turbulence model which is used in

application is introduced. Finally informations about volume of fluid method for modelling

of free surface flow , ILU factorization technique for solving of algebraic equation sets and

multigrid method which is the effective solution of algebraic equation sets are given.

In addition in this study, resistance of Wigley hull is calculated and wave systems are

observed at five different Froude number and results are compared with experimental

results.

Key Words: Computational fluid dynamics, hull, resistance
