Submarine Hydrodynamics
RENILSON, MARTIN (Prof) has been working in the field of Ship Hydrodynamics for over 35 years. He established the Ship Hydrodynamics Centre at the Australian Maritime College (AMC) in 1983, and was Director of the Australian Maritime Engineering Cooperative Research Centre in 1992. He started the Department of Naval Architecture & Ocean Engineering at AMC in 1996, which he ran until 2001 when he was appointed Technical Manager, Maritime Platforms & Equipment for DERA/QinetiQ in the UK. In 2007 Professor Renilson returned to Australia and set up his own company, conducting maritime related consulting. He also held a part time chair in hydrodynamics at AMC, now an institute of the University of Tasmania. In 2012 he was appointed inaugural Dean of Maritime Programs at the Higher Colleges of Technology, United Arab Emirates, to start maritime education for the country. He is also an Adjunct Professor in Hydrodynamics at the University of Tasmania, Australia.
This book covers specific aspects of submarine hydrodynamics in a very practical manner. The author reviews basic concepts of ship hydrodynamics and goes on to show how they are applied to submarines, including a look at the use of physical model experiments. The book is intended for professionals working in submarine hydrodynamics, as well as for advanced students in the field.
This revised edition includes updated information on empirical methods for predicting the hydrodynamic manoeuvring coefficients, and for predicting the resistance of a submarine. It also includes new material on how to assess propulsors, and includes measures of wake distortion, which has a detrimental influence on propulsor performance. Additional information on safe manoeuvring envelopes is also provided. The wide range of references has been updated to include the latest material in the field.

As they might spend significant time underwater in enemy territory, it is important to reduce the number of times they surface up. Because of the way anti-sub detection mechanisms work, every time a submarine dives down or surfaces up, the surrounding water particles are excited.
This excitation pattern helps can be used to spot submarines. Countries spend millions of dollars on installing expensive anti-sub detection systems to pick up on these vibrations and provide a warning.
Nuclear powered vessels and innovations in silent propulsion have helped reduce the engine and wake noise. An interesting anecdote in this regard is how despite the billions of dollars American warships spend on submarine detection, a Scandinavian submarine was able to sneak right up underneath it and score a direct hit during a war games training session.
With the advent of nuclear missiles and warships, submarines are also quickly making the shift to nuclear power. It is efficient, long-lasting, and considerably more silent with proper muffling. A full recharge of the core that powers the nuclear reactions may only be needed once in a cent
