Arakeri and published by . This book was released on 1971 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental results concerning force coefficients and cavity detachment points under various cavitating conditions on two geometrically similar bi-convex hydrofoils are presented. A linearized cavity flow theory with cavitation separation points determined from the assumption of smooth separation at the detachment point is presented and a comparison is made of these theoretical results with the experiments. Scaling problems with cavitation separation from smooth slender bodies are discussed. With the help of photographic studies three different types of cavitation separation from smooth bodies are proposed. (Author).

This book was released on 1987 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental investigations were made into the two major aspects of cavitation scale effects, susceptibility of the water to cavitation and flow field effects. In situ investigations of marine cavitation nuclei populations were made using underwater holography. Relatively high bubble concentrations during calm sea conditions, and their population inversion below the thermocline where organism activity was high, indicate a possible biological source of bubble production. Measured bubble sizes can be used to indicate that the average tensile strength of the ocean waters examined should be on the order of several thousands Pascals, with a minimum expected value of about one hundred Pascals. A concentration of at least 3 bubbles per cu cm in the 5 to 20 micrometers radius range is needed in test facility water to model marine conditions. The inception processes in a turbulent free shear layer were examined at Reynolds numbers up to 2 million. Two distinct types of vortex motion were evident, the primary spanwise and the secondary longitudinal vortices. Cavitation inception occurs in the secondary shear layer vortices and more fully developed cavitation is visible in both structures. A Rankine vortex model indicates that the secondary vortex strength is less than 10% of that of the primary structure.

Available in PDF, EPUB and Kindle. Book excerpt: The power sector has undergone a liberalization process both in industrialized and developing countries, involving market regimes, as well as ownership structure. These processes have called for new and innovative concepts, affecting both the operation of existing hydropower plants and transmission facilities, as well as the development and implementation of new projects. At the same time a sharper focus is being placed on environmental considerations. In this context it is important to emphasize the obvious benefits of hydropower as a clean, renewable and sustainable energy source. It is however also relevant to focus on the impact on the local environment during the planning and operation of hydropower plants. New knowledge and methods have been developed that make it possible to mitigate the local undesirable effects of such projects. Development and operation of modern power systems require sophisticated technology. Continuous research and development in this field is therefore crucial to maintaining hydropower as a competitive and environmentally well-accepted form of power generation.

Available in PDF, EPUB and Kindle. Book excerpt: Maritime Technology and Engineering 3 is a collection of papers presented at the 3rd International Conference on Maritime Technology and Engineering (MARTECH 2016, Lisbon, Portugal, 4-6 July 2016). The MARTECH Conferences series evolved from biannual national conferences in Portugal, thus reflecting the internationalization of the maritime sector. The keynote lectures and the papers, making up nearly 150 contributions, came from an international group of authors focused on different subjects in a variety of fields: Maritime Transportation, Energy Efficiency, Ships in Ports, Ship Hydrodynamics, Ship Structures, Ship Design, Ship Machinery, Shipyard Technology, afety & Reliability, Fisheries, Oil & Gas, Marine Environment, Renewable Energy and Coastal Structures. This book will appeal to academics, engineers and professionals interested or involved in these fields.
