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).

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 One dimensional Compressible Flow in Vaneless Diffusers of Radial and Mixed flow Centrifugal Compressors Including Effects of Friction Heat Transfer and Area Change written by John D. Stanitz and published by . This book was released on 1952 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis method and a design method are developed for one-dimensional, compressible flow with friction, heat transfer, and area change in vaneless diffusers with arbitrary profiles in the axial-radial plane. In the analyis method the varations in fluid properties are determined as a function of radius for a prescribed variation in diffuser wall spacing with radius. In the design method the variation in effective diffuser wall spacing is determined as a function of radius for an arbitrary prescribed variation in one fluid property. As a result of numerical examples it is concluded that: (1) The friction losses in most vaneless diffuser designs are considerable and these losses result from the usually large ratios of wetted surface to flow area in vaneless diffusers. (2) Vaneless diffuser efficiencies can be improved by increased compressor flow rates for a given impeller tip radius.

This book was released on 1949 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the most accurate determination of compressor performance from measured static pressures, a wall-surface friction correction is required. At diffuser diameters of about 1 1/2 impeller diameters or greater, the compressor efficiencies determined from measured static pressures showed good agreement with those based on measured total pressures.

This book was released on 2006 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The operation of centrifugal compressor systems is limited at low-mass flow rates by fluid flow instabilities leading to rotating stall or surge. These instabilities limit the flow range in which the compressor can operate. They also decrease the performance and efficiency of the compressor. Experiments were conducted to investigate a model of radial vaneless diffuser at stall as well as stall-free operating conditions."--Abstract, p. iii.
