Abstract
In this research, we primarily focus on an optimal design of a
wave-damping stern for a container ship .To generate a basis for
designing a new stern form or to improve the hull form, a series of stern
by a parametric-design method is conducted on a container ship provided
by a shipyard . Simultaneously , a CFD method is introduced to predict
the ship resistance . The applized CFD method is validated by comparing
with HSVA experimental results with numerical prediction .The margin
of error is less then 5% for grids with 1 million cells grid .As the number
of cell increases to 4 million , the margin of error further reduces to
smaller than 1%.
Both numerical prediction and experimental result obtain on the
NTU towing tank indicate that the new stern form is better than the basic
form by reducing the crest of stern wave.
Besides , this research creates a series of hull forms by varing with
stern frame angle longitudinally, crosswise with cross-section properties
and the elongation of ducktail which are for the sake of researching on
the wave-damping effect of the new stern shape.
