Book excerpt: Abstract: Two new low-drag hydrofoils for operation at zero cavitation number are derived by the application of the Tulin-Burkart linearized theory. The two-dimensional lift-drag ratios of these two hydrofoils operating at design angle of attack are shown to be, theoretically, about 45 and 80 percent greater than the Tulin-Burkart configuration. A simplified calculation of the location of the upper cavity streamline for arbitrary configurations is also presented.

Book excerpt: Abstract: The existing two-dimensional theory for the characteristics of supercavitating hydrofoils operating at zero cavitation number is modified to include the effects of camber, aspect ratio, and depth of submersion. For a comparison with the theory, two aspect-ratio-1 hydrofoils, a flat plate and one with a cambered lower surface, were tested by operating them near the water surface so that their upper surfaces were completely ventilated. The data obtained verified the theory to within 3 percent. Some experimental data are also presented for the models operating at nonzero cavitation number for both air and water-vapor-filled cavities.

Book excerpt: Advances in Hydroscience, Volume 1 considers the physical theories and mathematical analyses of a broad spectrum of specialized subjects in various branches of hydroscience, including hydrodynamics, hydrology, hydrochemistry, hydrophysics, hydrobiology, hydrometeorology, oceanology, hydrogeology, naval science, and water resources. This book contains five chapters, and begins with a presentation of scientific and engineering advances in the field of sonar and hydroelasticity. The following chapter deals with the fundamental principles and concepts of statistical hydrodynamics in porous media and their significance in various engineering applications. These topics are followed by a discussion on the concepts of theoretical incompressible fluid dynamics, with a special emphasis on the field of hydroballistics. The last chapter provides first a brief introduction to the basic principles and fundamental equations of well hydraulics, followed by a survey of its importance to water economy in arid and semiarid regions of the world. This book will be of great value to research workers and practitioners in the interdisciplinary field of hydroscience.
