Fundamentals of Ship Hydrodynamics: Fluid Mechanics, Ship Resistance and Propulsion Lothar Birk, University of New Orleans, USA Bridging the information gap between fluid mechanics and ship hydrodynamics Fundamentals of Ship Hydrodynamics is designed as a textbook for undergraduate education in ship resistance and propulsion. The book provides connections between basic training in calculus and fluid mechanics and the application of hydrodynamics in daily ship design practice. Based on a foundation in fluid mechanics, the origin, use, and limitations of experimental and computational procedures for resistance and propulsion estimates are explained. The book is subdivided into sixty chapters, providing background material for individual lectures. The unabridged treatment of equations and the extensive use of figures and examples enable students to study details at their own pace. Key features: Covers the range from basic fluid mechanics to applied ship hydrodynamics. Subdivided into 60 succinct chapters. In-depth coverage of material enables self-study. Around 250 figures and tables. Fundamentals of Ship Hydrodynamics is essential reading for students and staff of naval architecture, ocean engineering, and applied physics. The book is also useful for practicing naval architects and engineers who wish to brush up on the basics, prepare for a licensing exam, or expand their knowledge.
Autorentext
LOTHAR BIRK has more than two decades of experience teaching ship and offshore hydrodynamics, first at the Technische Universität Berlin and now at the University of New Orleans (UNO). Fascinated by the world of boats and ships, he studied naval architecture at Technische Universität Berlin (TUB) in Germany. After graduation he worked at TUB as a research scientist completing projects and teaching classes related to hydrodynamics and optimization of ship and offshore structures. In 2004, he joined the faculty of the School of Naval Architecture and Marine Engineering at UNO where he teaches classes in ship resistance and propulsion, propeller hydrodynamics, experimental, numerical and offshore hydrodynamics as well as computer aided design and optimization. His passion for teaching has earned him several awards by student organizations.

BRIDGING THE INFORMATION GAP BETWEEN FLUID MECHANICS AND SHIP HYDRODYNAMICS Fundamentals of Ship Hydrodynamics is designed as a textbook for undergraduate education in ship resistance and propulsion. The book provides connections between basic training in calculus and fluid mechanics and the application of hydrodynamics in daily ship design practice. Based on a foundation in fluid mechanics, the origin, use, and limitations of experimental and computational procedures for resistance and propulsion estimates are explained. The book is subdivided into fifty-one chapters, providing background material for individual lectures. The unabridged treatment of equations and the extensive use of figures and examples enable students to study details at their own pace. Key features:
