Download or read book Mitigation Of Hydrodynamic Resistance Methods To Reduce Hydrodynamic Drag written by Marc Perlin and published by World Scientific. This book was released on 2014-11-18 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text presents the state of the art in friction drag/resistance reduction technologies for BODIES and crafts operating in liquids at and beneath the free surface. It is useful for professionals with backgrounds in advanced fluid dynamics as well as by academics teaching introductory graduate courses in this area. Active control of resistance will include a discussion of friction reduction, for example through the injection of gas that can form air layers and polymers that initially reside adjacent to the hull, including the use of partial and super cavities. The book discusses passive resistance control achieved through changes in the overall hull shape and appendages, including the application of lifting bodies, bulbous bows, and stern flaps. It also addresses passive reduction of skin friction through the application of hull coatings and other elements of hull husbandry.

Download or read book An Experimental Investigation of Devices for Reducing the Hydrodynamic Resistance of Amphibious Vehicles written by D. N. Contractor and published by . This book was released on 1965 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were run on a model of a typical amphibious vehicle in order to determine bow configurations which would result in lower vehicle resistance. Tests were run with both fixed and towed models. The Froude number was varied and the resistance and trim angle, if any, were measured. Five bow plans and four bow profiles were chosen and eight bows were built and tested in a fixed position. Four of these bows were representative of the bows of present prototype craft and the other four were not. The latter bows all had less resistance than the best typical bow at a Froude number of 0.55. Towing tests of these two bows corroborated the results of the fixed model tests. (Author).

Generation of low volume flow air cavities under the hull of displacement, semi displacement and planing vessels are introduced together with theoretical and empirical analysis and design methods. Resistance reduction, power reduction and fuel efficiency are covered for both displacement and high speed vessels. Air layer and air cavity effects on vessel static and dynamic stability are covered, linked to regulatory requirements such as IMO. Seaway motions and reduced impact load of high speed craft in waves are discussed including model test results. Integration of propulsion systems for optimum powering is summarized. A design proposal for a wave piercing air cavity craft is included in an appendix. A comprehensive listing of document resources and internet locations is provided for further research.

Download or read book A guide to forest water management written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-08-24 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many people worldwide lack adequate access to clean water to meet basic needs, and many important economic activities, such as energy production and agriculture, also require water. Climate change is likely to aggravate water stress. As temperatures rise, ecosystems and the human, plant, and animal communities that depend on them will need more water to maintain their health and to thrive. Forests and trees are integral to the global water cycle and therefore vital for water security – they regulate water quantity, quality, and timing and provide protective functions against (for example) soil and coastal erosion, flooding, and avalanches. Forested watersheds provide 75 percent of our freshwater, delivering water to over half the world’s population. The purpose of A Guide to Forest–Water Management is to improve the global information base on the protective functions of forests for soil and water. It reviews emerging techniques and methodologies, provides guidance and recommendations on how to manage forests for their water ecosystem services, and offers insights into the business and economic cases for managing forests for water ecosystem services. Intact native forests and well-managed planted forests can be a relatively cheap approach to water management while generating multiple co-benefits. Water security is a significant global challenge, but this paper argues that water-centered forests can provide nature-based solutions to ensuring global water resilience.
