The members of the committee responsible for the report were chosen for their special competences and with regard for appropriate balance. This report has been reviewed by a group other than the authors according to procedures approved by a Report Review Committee consisting of members of the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine. The National Academy of Sciences is a private, nonprofit, selfperpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Frank Press is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Robert M. White is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Samuel O. Thier is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy's purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Frank Press and Dr. Robert M. White are chairman and vice chairman, respectively, of the National Research Council.

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 fortysix wellqualified 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.
