It coincided with the inauguration of the new model basin at the Bassin d'Essais des Carènes. 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 Carènes. 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, first-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 François Lefaudeux (Bassin d'Essais des Carènes), 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 people. 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 Carènes), 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 Carènes 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 onsite 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 21st century. Edwin P.Rood Office of Naval Research the authoritative version for attribution.

Please use the print version of this publication as OPENING REMARKS—RADM JAY M.COHEN, USN CHIEF OF NAVAL RESEARCH viii OPENING REMARKS—RADM JAY M.COHEN, USN CHIEF OF NAVAL RESEARCH Admiral Lafaudeaux, first allow me to express what a personal honor it is for me to address this distinguished gathering. I am pleased that the Office of Naval Research, which I lead, has cosponsored this important symposium along with the National Research Council and the Bassin d'Essais des Carènes. The brochure for this twenty-third symposium invites us to “a week of exchange, debates, and sharing of experiences in the field of Naval hydrodynamics”—a worthy and necessary goal indeed! My personal experience started thirty-six years ago, when as a boy of seventeen I left home and entered the United States Naval Academy at Annapolis. I joined the Navy to see the world (places and people), to drive submarines at sea, and to design future ships when ashore. I did not realize at the time how fulfilling and challenging my choices would be. At Annapolis I studied naval architecture. I was enamored with the idea of placing a blank sheet of paper on a drafting table, using flexible plastic batons and lead-weighted ducks to hold the baton down in place while I used a pencil to draw a new hull form on the paper. What personal freedom of design and power: it was science, engineering, and art all in one. Computers of the day available to me couldn't compete with my mind, eye, and hand. The Naval Academy tow tank was small, simple, and reliable, and free to use if I helped the technical assistant with his chores. Models were pulled at consistent force by a cable and a weight that fell down a shaft equal to the length of the tank. Gravity was constant. The weights and models varied. None of my line drawings became actual ships and I didn't make any hydrodynamic breakthroughs as a result of my tow tank work, but I learned about ships, propulsion, seakeeping, and experimentation—and it was fun! Science should be fun. As a midshipman I spent two summers at sea. Once as a junior midshipman performing all the menial chores of a deck hand, cook, and engineer on the Coast Guard sail-training barque Eagle, I sailed from Connecticut, through the Panama Canal, and ended up after two weeks in Seattle. What an experience to run before a storm with all twenty-two sails straining and the lee sail awash as the Eagle moved smoothly through the water at her maximum hull speed. My second cruise was on a World War II vintage diesel electric submarine out of San Diego. The captain of that ship was experienced, confident, and a great officer and mariner. He allowed the five young midshipmen on board to drive his boat, learn by making or nearly making mistakes, and then learn some more. That submarine was my first experience with electric ship propulsion, but a far cry from the all-electric ships the United States Navy is designing today. Some of you know that submarine's commanding officer, then a lieutenant commander—he is Rear Admiral Brad Mooney, a retired former Chief of Naval Research. I would not be here if it were not for his inspiration. For those wondering when the “expressive” portion of this talk will end and begin to focus more on the specifics and challenges of hydrodynamics, just one more sea story. After two years at sea on a diesel submarine as an ensign in the Navy, I attended MIT and Woods Hole Oceanographic Institution. I studied naval architecture, marine engineering, and ocean engineering. It was 1970, and computers were just beginning to be used for seakeeping and computational fluid dynamics. Most of my textbooks were mimeographed copies of professors' class notes—professors, I might add, who came from all around the world, like the participants in this symposium. MIT has a sophisticated medium-sized tow tank that I used for my thesis work, the recovery of submersibles through the air-sea interface in a seaway. While computers were being used even then, tank testing remained essential for accurate validation of full-scale ship characteristics before ship production. One of the dangers of inviting an old naval officer to speak is that he has many more sea stories than a junior officer. I won't bore you any longer. It is most appropriate that this symposium is being held in France. Both the United States and the French Republic were born of revolution. Today we are experiencing a revolution in ship design, construction, and operation. And your efforts have made it possible, with enormous gains still ahead. Computers of incredible sophistication, power, and speed, available at affordable prices, have made into a worldwide reality what were previously only imagined hull forms, propulsors, materials, navigational accuracy, maintenance and performance monitoring and prediction, and sophisticated damage control in minimally manned, highly automated ships. I may be nostalgic for hand-drawn ship plans and sailing ships, but the reality and future possi-bilities are far more exciting and challenging. the authoritative version for attribution. We must rise to that challenge! There is still much to learn. People still program the computers, and despite our best efforts to model complex hydrodynamic effects such as turbulence, boundary-layer

As the navies of the world enter the 21st century, new high-speed wave-piercing multihull forms are appearing. Ensuring stealth in the face of all means of detection is a high priority. The cost of manpower and fuel are key components in system and design decisions. Human factors such as highly trained and stressed sailors, trying to perform difficult mental and physical tasks in a seaway, bring psychologists and hydrodynamicists together. Improved reliability of equipment—from hull coatings to seawater pumps—and a corresponding reduction in maintenance are essential if we are to afford future navies of any significant size and capability. Electric drive, decoupled from the tyranny of the mechanical shaft and propeller drive, could mean that the designer is free to experiment with ideal hull forms pushed or pulled by podded or shrouded propulsors, attached to the hull but operating in the free stream of un disturbed water away from the hull. Ceramic finishes and/or polymers may give us even greater propulsion efficiencies. The new French “Lafayette” frigate shows how such ships can be both functional and beautiful. These are the challenges that revolutions are made of. The time is right, the time is now—use these precious days in Val de Reuil to share great thoughts to motivate even greater developments in the complex and challenging field of hydrodynamics. Let another revolution in ship design begin! the authoritative version for attribution.

"Vive la Revolution!" was the theme of the Twenty-Third Symposium on Naval Hydrodynamics held in Val de Reuil, France, from September 17-22, 2000 as more than 140 experts in ship design, construction, and operation came together to exchange naval research developments. The forum encouraged both formal and informal discussion of presented papers, and the occasion provides an opportunity for direct communication between international peers.

This book includes sixty-three papers presented at the symposium which was organized jointly by the Office of Naval Research, the National Research Council (Naval Studies Board), and the Bassin d'Essais des Carènes. This book includes the ten topical areas discussed at the symposium: 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.
