Download or read book Test Evaluation of Stationary and Rotating Diffusers for a High Pressure Ratio Radial Compressor written by Colin Rodgers and published by . This book was released on 1977 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of a free rotating vaneless/vaned diffuser (F.R.D.) for a nominal 1.9 pps, high pressure ratio, single stage radial compressor was completed, together with a comparative conventional stationary vaneless/vaned optimum channel diffuser. Both types of diffuser were subsequently fabricated and individually installed in an existing turbodrive compressor rig for comparative performance evaluation. At 100% corrected design impeller speed, equal to 62,000 rpm, the peak pressure ratio and adiabatic efficiency for the stationary and F.R.D. systems were 7.91 and 72.6% compared to 7.43 and 70%, respectively. Impeller efficiency was not repeatable and reduced 3.8% at design speed with the F.R.D. installed, probably as a result of different radial clearance settings. Overall peak vaneless/vaned diffuser static pressure recovery was essentially the same (0.61) at design speed with either the stationary or F.R.D. systems. (Author).

Download or read book Radial Flow Turbocompressors written by Michael Casey and published by Cambridge University Press. This book was released on 2021-06-10 with total page 789 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to the theory and engineering practice that underpins the component design and analysis of radial flow turbocompressors. Drawing upon an extensive theoretical background and years of practical experience, the authors provide descriptions of applications, concepts, component design, analysis tools, performance maps, flow stability, and structural integrity, with illustrative examples. Features wide coverage of all types of radial compressor over many applications unified by the consistent use of dimensional analysis. Discusses the methods needed to analyse the performance, flow, and mechanical integrity that underpin the design of efficient centrifugal compressors with good flow range and stability. Includes explanation of the design of all radial compressor components, including inlet guide vanes, impellers, diffusers, volutes, return channels, de-swirl vanes and side-streams. Suitable as a reference for advanced students of turbomachinery, and a perfect tool for practising mechanical and aerospace engineers already within the field and those just entering it.

Download or read book Analytical Experimental and Mechanical Evaluation of Free Rotating Vaneless Diffusers written by and published by . This book was released on 1972 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental testing of a model free rotating vaneless diffuser rig to determine diffuser loss coefficients and static pressure recovery under braked and free rotating conditions was conducted. The rig was operated at entry Mach numbers up to unity with both vaned and vaneless diffusers installed downstream. Two rotating diffuser widths were tested. A significant improvement in diffuser performance was achieved under free rotating conditions, even though large wakes generated by upstream stationary swirl nozzles were present. Overall static pressure recovery for the complete diffusion system increased approximately 20%, at free rotating conditions corresponding to a tangential velocity ratio (diffuser/incident stream) of 0.43. The total pressure loss reduction between braked and rotating conditions correlated with theoretical studies. A mechanical design study to examine methods of integrating the rotating diffuser into a complete gas turbine was also conducted and a feasible preliminary design identified.
