FUNDAMENTALS OF SHIP HYDRODYNAMICS

The present title is intended to cover the existing info gap between the ship hydrodynamics and the science of fluid mechanics. It has been written as a sort of textbook to be used by the students of naval architecture, dealing with the ship hull resistance and ship propulsion areas.

The idea was to connect the essential fluid mechanics training with the practical applications of the hydrodynamics, focusing specifically on the day-to-day practice of designing vessels. The estimates of the ship hull resistance have been explained in detail on the basis of the procedures used in the fluid mechanics; all necessary material has been provided in the sixty chapters of the volume.

The entire range of the applications has been covered with the remarkable depth that would enable easy and comfortable self-study process. The text part of the book is supplemented with the numerous figures and data tables. We would definitely treat the present title as the must-read for all students of naval architecture and ship design, as well as the ocean engineering, considering the number of topics covered by the author. It would also serve as an invaluable training and reference source when preparing for the relevant examinations.

SHIP MOTIONS AND CAPSIZING IN ASTERN SEAS

This is a good collection of the carefully selected works, provided by the recognized experts on the subject of the ship motions. It reflects the results of the efforts of analytical study and experimental research applied to the vessel motion in the rough seas. As a result of the study, the motion anomalies have been revealed upon conducting the model analysis, and these motions had never been notices earlier, based on the standard linearized theory.

There have been so many tests completed with the radio-controlled vessel models, and using the wide array of techniques. In addition to that, the document presents results of the comparisons conducted between the ship motions determined in the course of the experiments, and the predictions made based on the linear strip theory.

Long story short, the content of the present volume will be of practical interest and use to all those willing to study the ship motion in detail and with the emphasis made on the extreme seas and rough weather conditions. Make sure that you go through the pages of the document since it provides wealth of information that is very difficult to find somewhere else, and the live examples worked by the professional researchers.

RESISTANCE OF SHIPS AND SCREW PROPULSION

The author of this classical work developed it with the intention to give students a sort of compact yet informative treatise that would cover all the aspects of the ship hull resistance and propulsion and that would contain all necessary formulae, tables and other data for making correct estimates. His efforts eventually resulted in the present title that gained popularity among students of naval architecture.

There are six basic chapters in this volume, starting with the general information about the hull resistance, where the essentials are explained including but not limited to the eddy and skin resistance, Froude’s and Rankine’s methods, phenomena of waves, trochoidal waves, squat and shallow water effects etc. The second chapter deals with the propellers and provides all important definitions and formulae with proper and easily understandable explanations.

After that, the author proceeds with the analysis of the mutual reactions between ship’s hull and propeller, including the thrust deduction; later, the analysis of trials is given together with the average results. Two other chapters of the publication are devoted to the power of ships and design of the ship’s propellers.

THE RESISTANCE AND PROPULSION OF SHIPS

The main body of this classic publication is arranged in six chapters. The first chapter is dealing with the ship resistance itself, including the general ideas on that and stream lines with their geometry, one of the deeply immersed planes, skin-resistance, wave-making resistance, Froud’s experiments, increase of the ship’s hull resistance due to the shallow and/or rogue water, the influence that the shoals, banks, currents and slops have on the resistance, and other relevant items.

The second chapter is devoted to the ship propulsion, and here such important matters as propellers and their propulsive actions, hydraulic propulsion, screw turbines/propellers etc. , are covered in detail. The objective of the third chapter is to address reaction between the ship’s hull and the propeller, with due attention paid to the constitution of the wake, analysis of the power that would be required for the propulsion of particular ship, indicated thrust, mean pitch and mean slip, negative apparent ship etc.

The remaining three chapters tell readers about the design of the ship propeller, powering ships and, of course, trial ships. Although released more than a century back, the content of the book retails its relevance today.

CREATING SHAPES IN CIVIL AND NAVAL ARCHITECTURE

The content of this volume is mainly based on the results obtained in the course of the international Workshop which took place in Berlin and dedicated to creating of the shapes in both naval and civil architecture. The authors of the paper are presenting the very final version of the fourteen articles that have been presented at that time together with four relevant appendices.

Subject workshop was intentionally held to lay the certain basics in a comparative study of the history of technical knowledge in two above mentioned disciplines. We know that the naval architecture is treating the conception, design and subsequent realization for the maritime structures. The subject of creating shapes was considered a focal interest point for the comparisons carried out between two above mentioned disciplines due to the important role it plays in development of the objects.

The discussions and presentations that took place during that workshop and then included in this volume in the form of results are following such objectives as collection and documenting of the sources of shape creating-related knowledge, classification of the procedural and practical knowledge, enumeration of the important milestones, placing priorities related to the design and construction of the objects, relevant historical changes, comparison of different styles and methodologies of shape design, terminology, real life case studies etc.

SHIP RESISTANCE AND FLOW

One of the most serious problems of contemporary naval architecture is the correct prediction of the resistance of the newly developed designs at the earlier stages of the project. At the time of the ordering of the new vessel, a contract that contains the technical specification is signed between the yard and the future ship owner. Among the most important specifications is the contract speed of the ship, i.e. the speed attained to the particular power consumption during the sea trials carried out straight after the delivery.

Subject trials are supposed to be carried out under the ideal weather conditions. However, in the real life numerous corrections have to be made to the influence of the various environmental factors. In case corrected speed of the vessel appears to be lower than the one specified in the contract, the shipyard will have to pay a penalty to the ship owner, and this penalty will mainly depend on the difference noted between the contract speed and the speed achieved during the trials.

And, should this difference be too large, ship owner may even refuse to accept the newly built ship. This volume covers all aspects of the ship resistance and flow, including the governing equations, resistance decomposition, types and proof of similarity, flow around the ship hull. experimental prediction of the hull resistance and its numerical prediction and others.
