Collected Experimental Resistance Component and Flow Data for Three Surface Ship Model Hulls

Download or read book Collected Experimental Resistance Component and Flow Data for Three Surface Ship Model Hulls written by J. H. McCarthy and published by . This book was released on 1985 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resistance and flow data are summarized for models of selected surface ship hull forms. The data were obtained from more than 20 experimental facilities worldwide. These data were collected to provide a base for comparisons between experimental findings at several institutions under various model conditions and for validation and further development of theoretical prediction methods. The most extensive data bases presented are for the Wigley parabolic hull and the Series 60, Block 0.60 hull. These data include measurements of total resistance, wave pattern resistance and spectra, wake survey viscous resistance, hull pressure, hull shear stress, and boundary-layer velocities. More limited data for some of the global types of measurements are also reported for ATHENA, a high-speed transom stern hull. Data for one additional hull, the very full form HSVA tanker, is not reported here because of the limited amount of available data. Microfiche copies of all detailed data reports prepared by contributing organizations, on which the summary is based, are included as appendices. Despite differences in measurement techniques, most laboratories produce similar results for the same hull under similar test conditions; however, caution should be exercised when using very small models.
