Available in PDF, EPUB and Kindle. Book excerpt: How does cavitation start? Presently, the nucleus theory provides the answer to this fundamental question. However the idea of nuclei contains inaccuracies that cannot be rationalized. Recent Developments in Cavitation Mechanisms discusses the uncertainties surrounding the nucleus theory, and proposes another theory of cavitation mechanism. Characteristically, the new theory is based on recent discoveries of cavity generation phenomena in separating flows. This book consists of chapters that introduce topics such as unsoundness of cavitation nuclei, and phenomena of cavity generation on walls of flow separation in hydraulic oil and water flows. Subsequent chapters cover the mechanism of cavity generation at point of flow separation, nucleation by contact motion between solids in liquid and a proposal of new cavitation mechanism based on flow separation and solid contact. The final chapters present the demonstration of a new mechanism in the hydraulic poppet valve and a concluding summary. proposes a new mechanism of cavitation inception in liquid machines describes in detail phenomena of cavity generation at point of flow separation recently discovered by the author discusses peculiar properties of flow separation as cause of cavity generation presents abundant experimental data of incipient cavitation obtained with high resolution of time and space provides supplementary materials of slow motion videos that can help understand the very rapid and minute phenomena of cavity generation which has been discovered by the author and will be still unfamiliar to many

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.

Download or read book Cavitation Damage Mechanisms Review of Literature written by D. C. Wiggert and published by . This book was released on 1980 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is a companion volume to 'Cavitation Damage Mechanisms: Experimental Study of Cavitation in a Spool Valve.' The state-of-the-art available in the literature is reviewed relative to occurrence of cavitation, the effects of dissolved and free gas, and so-called secondary aspects of combustion/sono-luminescence and electrical/chemical effects. It should be noted that a paucity of literature exists with regard to cavitation in oil hydraulic systems; consequently much of the material discussed deals with water as the working fluid. Throughout the text clear distinctions are made as to the fluid under discussion. The small number of references which do relate to oils are covered as thoroughly as deemed necessary. The last topic to be presented concerns cavitation in hydraulic actuators. This is a markedly different type of cavitation than is dealt with in the present experimental study; it is included for completeness and due to the fact that it can be a potential problem in control system performance, although most often it creates no permanent mechanical damage to actuator components.

Download or read book Cavitation Damage Mechanisms Experimental Study of Cavitation in a Spool Valve written by C. S. Martin and published by . This book was released on 1980 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cavitation has been investigated in directional control valves in order to identify damage mechanisms characteristic of components of aircraft hydraulic systems. Extensive tests were conducted in a representative metal spool valve and in a model three times larger. Both valves are well instrumented for the purpose of accurately measuring mean quantities as well as detecting the onset and extent of cavitation once it developed. Non-cavitating data taken with both valves showed that the position of the high-velocity annular jet issuing from the orifice shifted orientation depending upon valve opening and Reynolds number. By means of high-frequency response pressure transducers strategically placed in the valve chamber of each test valve cavitation could be sensed by the correlation of noise with a cavitation index. Cavitation inception could be detected by comparing energy spectra for a fixed valve opening and a constant discharge. Another sensitive indicator of cavitation inception is the ratio of cavitating to non-cavitating spectral densities. The incipient cavitation index as defined in this investigation correlates well with the Reynolds number for both valves. Once cavitation develops, an accelerometer properly located on the cavitating component can be as sensitive to cavitation noise as a pressure transducer. Energy levels under developed cavitation were affected to some extent by temperature differences.

Download or read book Advances in Environmental Engineering Research in Poland written by Małgorzata Pawłowska and published by Routledge. This book was released on 2021-07-29 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: A side-effect of numerous anthropogenic activities involves unfavourable changes in the natural environment. The acquisition of natural resources, especially fossil fuels, solid waste and wastewater production, as well as emission of gases and particulate matter from industrial plants and means of transport contribute to disturbances in the natural cycles of elements between different parts of the environment. Local changes lead to global effects, changing the composition of atmosphere, its capacity for absorbing the infrared radiation and temperature, which has further repercussions in the form of weather anomalies, melting glaciers, flooding, migration or extinction of species, social problems, etc. These global changes can be mitigated by local remedial actions, simultaneously taken all over the world, including Poland. Only the joint efforts of communities from different countries can be successful in preserving the world as we know it for the future generations. Realisation of this task requires the cooperation of experts across many fields of science, environmental engineering being one of most relevant. It comprises the engineering actions taken to preserve the balance of the natural environment or restore it if degradation has occurred. This monograph presents several key issues related to the actions aimed at mitigating the negative impact on the environment connected with the acquisition and transport of energy, management of municipal and industrial wastes, as well as the impact of the industry on the aquatic and soil environment. This book is dedicated to academics, engineers, and students involved in environmental engineering, who are following the advances in the research on environmental aspects of energy production and waste management.
