Download or read book A Unified Method for Predicting the Performance of Subsonic Diffusers of Several Geometries written by Alfred Benjamin Cocanower and published by . This book was released on 1965 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unified performance prediction method was developed for class A diffusers. Class A diffusers have specified flow and geometry restrictions. The prediction method is a system of linear, first order differential equations. These equations embody the momentum equation, continuity equation, and two empirical correlation equations. In addition to the prediction method, two parameters were developed to characterize inlet conditions and separation respectively.

Download or read book Effect of Various Arrangements of Triangular Ledges on the Performance of a 23 Degree Conical Diffuser at Subsonic Mach Numbers written by Jerome Persh and published by . This book was released on 1954 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A brief investigation has been made to determine whether the use of annular ledges to promote turbulent momentum exchange will improve the performance of a short, wide-angle diffuser. Results are presented of tests of a 23 degree conical diffuser with a 2:1 ratio of exit to inlet area with both rough and smooth triangular ledges, approximately one-tenth of the inlet boundary-layer thickness in height, installed in succession from the inlet to the exit. The results show that, although the flow in the diffuser without ledges was very unstable, the presence of a roughness strip near the inlet, with or without additional ledges, assured stable flow. For the configurations investigated, the static-pressure recovery and the total-pressure-loss coefficient were either unaffected or only slightly impared by the installation of the ledges.

Download or read book AN EXPERIMENTAL INVESTIGATION ON THE EFFECT OF SUBSONIC INLET MACH NUMBER ON THE PERFORMANCE OF CONICAL DIFFUSERS. written by and published by . This book was released on 1966 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments were performed to determine the effect of subsonic inlet Mach number on diffuser performance and flow regimes for a wide range of conical diffuser geometries. As the Mach number is increased, the flow tends more toward separation in all cases. Diffuser performance maps are presented for three different inlet Mach numbers (S sub 1 = 0.25, 0.55, 0.70). There is no significant variation in the location of the line of maximum performance at constant length to inlet radius ratio, line alpha-alpha, with Mach number.

Download or read book Pressure Recovery Performance of Straight-Channel, Single-Plane Divergence Diffusers at High Mach Numbers written by and published by . This book was released on 1969 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements were made of the pressure recovery of straight-channel, symmetric, single-plane divergence diffusers with inlet Mach numbers between 0.2 and 1.0. Three aspect ratios, 0.25. 1.0, and 5.0, were studied for a range of length-to-throat width ratios and divergence angles of diffuser geometries near peak recovery. Diffuser performance maps are given that show pressure recovery as a function of diffuser geometry for fixed values of throat Mach number, throat blockage, and aspect ratio for the range of variables tested. Of significant importance to the designer is the alteration in the shape of the pressure recovery contours on the performance maps with variations in Mach number, blockage, and aspect ratio. Four subprograms have measured the effect of changes in diffuser inlet Reynolds number, boundary layer shape factor, asymmetric distribution of inlet blockage around the throat periphery, and the influence of rounded throat corners on the pressure recovery behavior of the straight-channel diffuser. The importance to the designer of a knowledge of how diffuser performance depends upon the diffuser geometric and inlet parameters is discussed. The application of channel diffuser performance data to the design of centrifugal compressor diffusers is described. The channel diffuser performance measured is compared with recovery performance of the channel diffusers in centrifugal compressors.

Download or read book The Design of High-Efficiency Turbomachinery and Gas Turbines, second edition, with a new preface written by David Gordon Wilson and published by MIT Press. This book was released on 2014-09-05 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of a comprehensive textbook that introduces turbomachinery and gas turbines through design methods and examples. This comprehensive textbook is unique in its design-focused approach to turbomachinery and gas turbines. It offers students and practicing engineers methods for configuring these machines to perform with the highest possible efficiency. Examples and problems are based on the actual design of turbomachinery and turbines. After an introductory chapter that outlines the goals of the book and provides definitions of terms and parts, the book offers a brief review of the basic principles of thermodynamics and efficiency definitions. The rest of the book is devoted to the analysis and design of real turbomachinery configurations and gas turbines, based on a consistent application of thermodynamic theory and a more empirical treatment of fluid dynamics that relies on the extensive use of design charts. Topics include turbine power cycles, diffusion and diffusers, the analysis and design of three-dimensional free-stream flow, and combustion systems and combustion calculations. The second edition updates every chapter, adding material on subjects that include flow correlations, energy transfer in turbomachines, and three-dimensional design. A solutions manual is available for instructors. This new MIT Press edition makes a popular text available again, with corrections and some updates, to a wide audience of students, professors, and professionals.
