Marine Propellers and Propulsion Third Edition


Year: 2012
Language: english
Author: J S Carlton FREng
Genre: Technical book
Edition: 3rd
Format: PDF
Quality: eBook
Pages count: 518
Description: Since the second edition was published in 2007 a number of
important changes have and are taking place which relate to
ship propulsion. Among these are the developments arising
from the IMO’s initiatives on the Energy Efficiency Design
Index and the bringing to fruition of their earlier work on
hull coatings stemming from their resolution on the subject
in 2001. In addition to these legislative initiatives is
a greater understanding of the physics associated with
cavitation development and collapse and its subsequent
erosive effects on propeller materials. Morover, some new
types of propulsor are being developed while in other
technical fields there is a greater awareness, for example, of
the effects of shipping activity on the behavior of marine
mammals. It is the intention of this third edition to capture
these and other developments that have occurred. In addition
a certain amount of rearrangement of the subject
matter has also taken place.
