Available in PDF, EPUB and Kindle. Book excerpt: Cavitation inception observations on two axisymmetric headforms were made in the DTNSRDC 36-inch water tunnel. The results indicate that cavitation inception on a headform with natural flow transition is significantly affected by the air content of the water. The effect of air content on cavitation inception on a headform with laminar separation is less pronounced. Visible cavitation inception never occurred at the locations of minimum static pressure but was observed to occur in the region of natural transition and the separated shear layer following laminar separation. It is concluded that both the viscous effects and cavitatable microbubble population are extremely important parameters governing the cavitation inception process. (Author).

This book was released on 1983 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cavitation inception observations were made in the DTNSRDC 36-inch water tunnel on three axisymmetric headforms with and without various turbulence stimulators installed. Direct measurements of transition, made on two of the headforms with and wothout distributed surface roughness, were found to correlate reasonably well with the computed spatial amplification factors, e to the Nth power with 7

Available in PDF, EPUB and Kindle. Book excerpt: Cavitation inception observations on a family of axisymmetric models were made in the 1.21 m water tunnel at the Applied Research Laboratory. Inception data were obtained on Schiebe headforms having diameters of 203.2 mm, 50.8 mm and 25.4 mm. The Schiebe headform has a C(pmin) = -0.75 and does not experience a separated boundary layer. Initially, cavitation inception data were obtained with no added roughness on the models. Then a distributed roughness of silicon carbide was glued to the nose of the two smaller models and additional cavitation inception data were obtained. Travelling-bubble cavitation was the type of cavitation observed near inception. Results show that it is possible to use a distributed roughness to increase the cavitation inception index to the indices found at higher Reynolds numbers. However the size and location of the roughness are very critical and the basic mechanisms which control this process need further investigation. This paper was presented at the 19th American Towing Tank Conference held in Ann Arbor, Michigan in July 1980. (Author).

Download or read book Cavitation written by Yves Lecoffre and published by Routledge. This book was released on 2021-10-08 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text deals with the concept that cavitation is the main limitation to the performance of hydraulic components. Topics covered include the vaporization of liquids due to high velocities or pressure fluctuations, and the effects of cavitation on the performances of rotary machinery. One chapter is devoted to cavitation noise which concerns many users, including surface ships and submarines, and the author finishes with some examples of the use of cavitation and subject-specific measuring techniques.
Download or read book Vapor Liquid Two Phase Flow and Phase Change written by Sarit Kumar Das and published by Springer Nature. This book was released on 2023-01-28 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive textbook highlights features of two phase flows and introduces the readers to flow patterns and flow maps. It covers a wide range of fundamental and complex subjects focusing on phase change processes like boiling, condensation or cavitation, and boiling phenomenon starting from pool boiling curves to heat transfer under nucleate boiling, film, and flow boiling. It also discusses themes such as numerical techniques for solving boiling and condensation as well as equipment used in industry for evaporation, boiling, and condensation. It includes pedagogical aspects such as end-of-chapter problems and worked examples to augment learning and self-testing. This book is a valuable addition for students, researchers, and practicing engineers.
