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.

This book was released on 1956 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigation of the unstable flow through four different types of diffusers were made. These were a pitot type intake, an axisymmetric model with a center body, a ramp and a scoop intake. The pitot intake was unique in that its only instability was at low and zero mass flow, and was of the acoustic organ pipe type. The other intakes were characterized by a high frequency oscillation at low mass flows, and a more complex phenomenon, known as buzz, at higher mass flows. It is believed that all diffusers which have a surface ahead of the inlet will have these two types of oscillation present to some degree, and that they will be the form as described in this report.

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.
