Application of CFD for the Prediction of Resistance Characteristics in Design of Hull Form of a Ship

Abstract

The accurate prediction of the hydrodynamic
characteristics of complex hull forms, primarily

in the areas of resistance, propulsion and sea-
keeping is one of the most important design

challenges faced by naval architects. This paper
focuses on the evaluation of resistance
characteristics which plays a significant role in
design of hull form of a ship through
Computational Fluid Dynamics (CFD).
Numerical simulation of resistances and flow
fields for incompressible turbulent free surface
flow (around the complex hull form model at
four different speeds) is dealt in this paper
using the Reynolds-Averaged Navier-Stokes
Equation (RANS) code by CFX. The Volume of
Fluid method (VOF) has been used with CFX
for capturing the free surface flow around the
ship model at various speeds. The standard k–є
turbulence model has been used in CFX code.
The grid generator ICEM CFD has been used
for building the multi-block grid for wave
generation and for the interactions of the ship
with the solution of the flow about the ship. It
indicates that numerical simulations are
creditable and the results obtained show a
fairly good agreement with the available
experimental data.
