Download or read book Cavitation and Tension in Liquids written by D. H. Trevena and published by CRC Press. This book was released on 1987 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cavitation is the process of formation of voids and clouds of bubbles in liquids under tension. Cavitation and the ability of liquids to withstand tension are therefore topics of considerable importance in a number of disciplines in pure and applied science. The monograph begins with a historical survey of early cavitation research which started with the pioneering work of F M L Donny and Marcelin Berthelot. The theoretical and experimental background to cavitation and the tensile strength of liquids - static and dynamic stressing of liquids and bubble studies - is then discussed before the practical consequences are considered. It is these 'applied' areas in which cavitation has most bearing on everyday life: engineers and marine architects must have an appreciation of the effects of cavitation on hydraulic machinery and ships' propellers while the cavitation properties of the liquid coolant can play a large part in the design and safety of fast nuclear reactors. In the medical field cavitation effects are met in joint cracking, decompression sickness and blood flow. The conclusion of the book, and a survey of the present state of knowledge, are presented by Professor H N V Temperley, who has had a lifetime's experience of cavitation research. This monograph will serve as a complete introduction to cavitation and tension in liquids for students of physics, engineering and chemical engineering. Researchers and teachers will find it a handy reference source. other_titles

Download or read book Liquids Under Negative Pressure written by A.R. Imre and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is possible to "stretch" a liquid and, when suitably prepared, liquids are capable of sustaining substantial levels of tension, often for significant periods of time. These negative pressure states are metastable but can last for days - long enough for substantial experimental investigation. This volume is a review of recent and current research into the behaviour of liquids under negative pressure. Part I deals with the thermodynamics of stretched liquids. Part II discusses the physical and chemical behaviour of liquids under negative pressure. Part III contains papers on the effect of negative pressure on the solidification of a liquid. Part IV is devoted to stretched helium and Part V discusses cavitation in various stretched liquids. Part VI deals with the effect of foreign substances on cavitation.

Download or read book Fundamentals of Cavitation written by Jean-Pierre Franc and published by Springer Science & Business Media. This book was released on 2006-01-22 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book treats cavitation, which is a unique phenomenon in the field of hyd- dynamics, although it can occur in any hydraulic machinery such as pumps, propellers, artificial hearts, and so forth. Cavitation is generated not only in water, but also in any kind of fluid, such as liquid hydrogen. The generation of cavitation can cause severe damage in hydraulic machinery. Therefore, the prevention of cavitation is an important concern for designers of hydraulic machinery. On the contrary, there is great potential to utilize cavitation in various important applications, such as environmental protection. There have been several books published on cavitation, including one by the same authors. This book differs from those previous ones, in that it is both more physical and more theoretical. Any theoretical explanation of the cavitation phenomenon is rather difficult, but the authors have succeeded in explaining it very well, and a reader can follow the equations easily. It is an advantage in reading this book to have some understanding of the physics of cavitation. Therefore, this book is not an introductory text, but a book for more advanced study. However, this does not mean that this book is too difficult for a beginner, because it explains the cavitation phenomenon using many figures. Therefore, even a beginner on cavitation can read and can understand what cavitation is. If the student studies through this book (with patience), he or she can become an expert on the physics of cavitation.

Available in PDF, EPUB and Kindle. Book excerpt: This research investigates effects of tensile stresses in liquids. Areas of application include bearing lubrication and polymer processing, in which liquids may be subjected to hydrostatic tension or large shear stresses. A primary thrust of this research is the development of a criterion for liquid failure, or cavitation, based upon the general state of stress in the liquid. A variable pressure, rotating inner cylinder, Couette viscometer has been designed and used to test a hypothesized cavitation criterion. The criterion, that cavitation will occur when a principal normal stress in a liquid becomes more tensile than some critical stress, is supported by the results of experiments with the viscometer for a Newtonian liquid. Based upon experimental observation of cavitation, a model for cavitation inception from crevice stabilized gas nuclei, and gaseous, as opposed to vaporous, cavitation is hypothesized. The cavitation inception model is investigated through numerical simulation, primarily using the boundary element method. Only Newtonian liquids are modeled, and, for simulation purposes, the model is reduced to two dimensions and the limit of negligible inertia is considered. The model includes contact line dynamics. Mass transport of dissolved gas through the liquid and in or out of the gas nucleus is considered. The numerical simulations provide important information about the probable nature of cavitation nucleation sites as well as conditions for cavitation inception. The cavitation criterion predicts cavitation in simple shear, which has implications for rheological measurements. It can cause apparent shear thinning and thixotropy. Additionally, there is evidence suggesting a possible link between shear cavitation and extrusion defects such as sharkskin. A variable pressure capillary tube viscometer was designed and constructed to investigate a hypothesized relationship between shear cavitation and extrusion defects. Results indicate that despite the occasional coincidence of occurrence of cavitation and sharkskin defects, cavitation cannot explain the onset of extrusion defects. If nuclei are removed, then liquids can withstand a negative hydrostatic pressure. A falling body viscometer has been constructed and used to investigate the effect of negative pressures on viscosity. It is found that current pressure viscosity models can be accurately extrapolated to experimentally achievable negative pressures.

Available in PDF, EPUB and Kindle. Book excerpt: Cavitation is a dangerous process which destroys objects in a fluid. Scientific description of this multifaceted phenomenon is based on almost every area of physics, and many interesting effects are connected with cavitation. The most intriguing of them is sonoluminescence – the light emitted from a cavitating fluid. This book presents a full-scale description of cavitation: from the basic thermodynamic principles to special phenomena associated with this complex process, from the dynamics of a single gas cavity to the catastrophic macroscopic manifestations, from the domestic observations to the nuances of X-ray spectroscopic research.

Download or read book Ultrafine Bubbles written by Koichi Terasaka and published by CRC Press. This book was released on 2021-09-15 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrafine bubbles (UFBs) are gas-filled bubbles with a diameter smaller than 1 μm. They are sometimes called bulk nanobubbles because these are not on a solid surface but inside a bulk liquid (water). They are already being used in commercial processes such as cleaning and plant cultivation. However, many mysteries still exist with respect to UFBs, such as mechanisms of stability, OH radical formation, and biological and medical effects. This is the first book on UFBs that reviews research done on them. It is helpful for those interested in the fundamentals of this emerging field and its applications, including cleaning, biological, medical, and dental students and researchers.
