Available in PDF, EPUB and Kindle. Book excerpt: A linear theory for the two-dimensional supercavitating flow past a flat hydrofoil heaving and pitching with small amplitudes in a choked tunnel is developed using the acceleration potential. It is supposed that the streamlines of the cavity always spring from the leading and the trailing edges of the foil and that the foil is inclined at a small angle to the oncoming flow. Also the pressure in the cavity is assumed to be constant. Force and moment coefficients are calculated as functions of reduced frequency and the ratio of tunnel height to chord length. The pressure disturbances caused by the unsteady motion in a tunnel studied far upstream; these are seen to depend on the chord-tunnel height ratio and reduced frequency. (Author).

This book was released on 1962 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Problems of symmetrical two-dimensional supercavitating flow about a thin wedge in a finite fluid with two parallel solid boundaries are solved by means of a linearized method utilizing the complex acceleration potential. The solution contains no singularity and, as a result, pressure is finite everywhere. The term indicating the effect of cavity pressure change on the drag which existed in the case of the flows with free boundaries is identical to zero when the boundaries are solid. It is also concluded that, in steady flow cases, the accuracy of the solutions using the linearized acceleration potential method is comparable to that using the linearized velocity potential method. The two methods give identical solutions when cavities are infinitely long. (Author).

Download or read book Unsteady Symmetrical Supercavitating Flows Past a Thin Wedge in a Jet written by C. S. Song and published by . This book was released on 1962 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Problems of symmetrical two-dimensional supercavitating flow about a thin wedge in a finite fluid with two free surfaces are solved by means of a linearized method utilizing the complex acceleration potential. Taking advantage of the symmetry, the otherwise doubly connected region is divided into two identical simply connected regions. An oscillatory-type motion as well as general types of unsteady motions are considered. The solution contains no singularity and, as a result, pressure is everywhere finite. The mathematical condition required for the existence of a singularity-free solution leads to an equation which gives the relationship between the cavity length and the cavitation number. The theoretical results are in good agreement with experimental data for the steadyflow case, but data for the unsteady case are not yet available. (Author).

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.
