FOREWORD
The Twenty-Third Symposium on Naval Hydro-
dynamics was held in Vat de Reuil, France, from
September 17-22, 2000. It coincided with the
inauguration of the new model basin at the Bassin
d'Essais des Carenes. This international symposium
was organized jointly by the Office of Naval Research,
the National Research Council (Naval Studies Board),
and the Bassin d'Essais des Carenes. This biennial
symposium promotes the technical exchange of naval
research developments of common interest to all the
countries of the world. The forum encourages both
formal and informal discussion of presented papers, and
the occasion provides an opportunity for direct
communication between international peers. More than
140 participants, including students, from 25 countries
attended the symposium. Sixty-three papers were
presented in the ten topical areas covered by the
symposium. Those topical areas are wave-induced
motions and loads, hydrodynamics in ship design,
propulsor hydrodynamics and hydroacoustics, CFD
validation, viscous ship hydrodynamics, cavitation and
bubbly flow, wave hydrodynamics, wake dynamics,
shallow water hydrodynamics, and fluid dynamics in the
naval context.
These topical areas were chosen because they
encompass recent scientific advances. For example,
f~rst-ever experimental results crucial for validating
software for modeling unsteady turbulent flow were
presented for a combatant in head waves. Another
paper described the successful use of sophisticated
large eddy simulation computations to predict the
pressure recovery in a submarine launch way. A third
discussed the use of experimentally validated large
eddy simulations to understand the physics underlying
nonstationary quantities for the hydrodynamic flow
over a lifting surface. This brief list illustrates the
quality and timeliness of the information presented in
the symposium.
Opening comments were delivered on the first
morning by Ronald D. Taylor (Naval Studies Board),
Admiral Franpois Lefaudeux (Bassin d'Essais des
Carenes), and RADM Jay M. Cohen, USN (Chief of
Naval Research).
The symposium featured invited lectures each
morning. These lectures were presented by Robert
Beck, Didier Frechou, Fred Stern, and Marshall Tulin
and covered seakeeping computations, propulsor
hydroacoustics, software verification and validation,
and wave breaking. At mid-week, the Twenty-First
Georg Weinblum Lecture was delivered by B. Molin,
who spoke on the topic "Numerical and Physical
Wavetanks: Making Them Fit" (not included in this
proceedings). These lectures by prominent
international experts set the pace for the technical
sessions that followed throughout each day.
The success of this symposium is the result of
diligence on the part of manY neonle. There was. of

course, the organizing and Paper Selection Committee
consisting of myself and Dr. Patrick Purtell (Office of
Naval Research), Mr. James Fein (Naval Sea Systems
Command), Dr. Ronald Taylor (National Research
Council), Dr. Stephane Cordier (Bassin d'Essais des
Carenes), Dr. William Morgan (David Taylor Model
Basin), Dr. Choung Lee (Pohang University of Science
and Technology), and Prof. Robert Beck (Journal of
Ship Research). The work of this committee was
certainly the cornerstone for the success of the
symposium.
The administrative preparation and execution, and
the production of this archival volume, were completed
with the support of Susan Campbell and Mary Gordon
of the Naval Studies Board, National Research
Council. Special appreciation is extended to Jennifer
McDonald and Diane McNeil, from my office, for
handling the abstract collection and the preparation of
the discussion sections.
The staff of Bassin d'Essais des Carenes is to be
congratulated for hosting this exemplary meeting.
Their care for the well-being of the participants is
greatly appreciated. Further appreciation is extended
to Pulsar Developpment, which provided essential on-
site administrative and organizational support.
For this program officer, the symposium marked
the end of a thirty-seven-year career in naval
hydrodynamics. I am very proud of the reputation of
this symposium series and of the associated
proceedings, which are recognized internationally as
the equivalent of a peer-reviewed journal and which
for more than a half century have served as the
document repository for leading-edge research in naval
hydrodynamics. I wish the best for the research
community as it embraces the challenges of the 21 st
century.
