PREFACE
The Fifth International Conference on Numerical Ship Hydrodynamics (INC5) was held
in Japan on 24-28 September 1989 at Hiroshima International Conference Center.
The Conference was sponsored jointly by the Shipbuilding Research Association of
Japan, and the following agencies in the Washington D.C. area: David Taylor
Research Center, Office of Naval Research and Naval Studies Board of the National
Research Council.
Over one hundred and ninety distinguished researchers from eighteen countries
gathered for this conference and forty-six well-qualified papers were presented.
Four keynote speakers were invited from outside the ship hydrodynamics community.
Their presentations provided a good balance between the computational fluid
dynamics and the experimental aspects of ship hydrodynamics. Because of the rapid
progress in the computational fluid dynamics and the rather long time span of four
years since the previous meeting, a large number of papers was submitted. For the
first time in these conferences, several parallel sessions were held. Even so,
many good papers had to be rejected. A special session for group discussions was
arranged to allow extended interchange of ideas among the specialists and to
deepen knowledge of ongoing research.
It was the paper committee's position that the validation of the computational
fluid dynamics was of primary importance. Thus, the committee asked all the
authors as a matter of policy to carry out an accuracy analysis with respect to
grid sizes and/or time steps, convergence check or test computations for less
complicated cases. This request influenced the content of the papers and resulted
in more careful numerical analysis, including comparisons with other results. It
was realized that this would entail additional expense and extra work for the
authors, but the committee believed that the resulting papers would reflect a
higher academic standard.
The committee enthusiastically supported the Workshop on Computational Fluid
Dynamics Validation organized by the International Towing Tank Committee (ITTC)
Validation Panel and Hiroshima University. This was a very well attended and
highly productive workshop. The results should have an impact on the three
components of CFD: analysis, computation, and experiment - the ACE of numerical
ship hydrodynamics.
The success of the Conference was due to the collective efforts of a large number
of individuals. The members of the Numerical Towing Tank Research Group in Japan
(NTG) helped greatly in hosting the conference in Hiroshima. Grateful
acknowledgements are also extended to the staff of Hiroshima University for their
devoted assistance. Special thanks go to Ms. Chizuko Kodera for her invaluable
organizing efforts. Without her skills the conference could not have been such a
technical success and a very pleasant experience.
