Available in PDF, EPUB and Kindle. Book excerpt: Tests in level ice on an idealized icebreaker bow in the shape of a simple wedge were conducted in the test basin. The horizontal and vertical forces on the wedge were measured, and floe size distribution in the wake of the wedge was observed. From the force measurements, the ice wedge/hull friction factor was calculated and found to be in general agreement with the friction factor measured in separate friction tests. The ice floe length and ice floe area measured in the current study were found to follow log-normal probability distributions defined by the length average L and area average A and corresponding standard deviations S sub L and S sub A. The results of these tests and other tests conducted at another facility showed that the ratios A/h squared and L/h (A = average floe area, L = average floe length, h = ice thickness) were, for the same type of model ice, directly proportional to the parameter sigma/gamma h (sigma = ice bending strength, gamma = specific weight of water) and sigma/gamma h, respectively, and independent of the velocity and ice strain modulus or ice characteristic length. However, the coefficients of proportionality appear to depend upon the type of model ice used in the tests. The ratios S-sub-L/A were independent of sigma/gamma h but varied with the bow shape and the type of ice. The available field data are not sufficient for meaningful comparison with the laboratory results. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Marine Propellers and Propulsion, Fourth Edition, offers comprehensive, cutting edge coverage to equip marine engineers, naval architects or anyone involved in propulsion and hydrodynamics with essential job knowledge. Propulsion technology is a complex, multidisciplinary topic with design, construction, operational and research implications. Drawing on experience from a long and varied career in consulting, research, design and technical investigation, John Carlton examines hydrodynamic theory, materials and mechanical considerations, and design, operation and performance. Connecting essential theory to practical problems in design, analysis and operational efficiency, the book is an invaluable resource, packed with hard-won insights, detailed specifications and data. - Features comprehensive coverage of marine propellers, fully updated and revised, with new chapters on propulsion in ice and high speed propellers - Includes enhanced content on full-scale trials, propeller materials, propeller blade vibration, operational problems and much more - Synthesizes otherwise disparate material on the theory and practice of propulsion technology from the past 40 years' development, including the latest developments in improving efficiency - Written by a leading expert on propeller technology, essential for students, marine engineers and naval architects involved in propulsion and hydrodynamics
