Book excerpt: This report describes work carried out at the Gas Turbine Laboratory at MIT during the period 10/20/89 - 10/19/92, as part of our multi-investigator effort on basic unsteady flow phenomena in turbomachines. Within the overall project four separate tasks are specified. These are. in brief: (1) The Influence of Inlet Temperature Nonuniformities on Turbine Heat Transfer and Dynamics; (2) Assessment of Unsteady Losses in Stator/ Rotor Interactions; (3) Unsteady Phenomena and Flowfield instabilities in Multistage Axial Compressors; IV. Vortex Wake-Compressor Blade Interaction in Cascades: A New Rapid Method for Unsteady Separation and Vorticity Flux Calculations.

Available in PDF, EPUB and Kindle. Book excerpt: Research is described on the fluid dynamic behavior of high performance diffusers for centrifugal compressors, with particular application to small gas turbine engine applications. Using a unique swirl generator, experiments have been carried out to define the performance and stall onset behavior of a modern discrete passage diffuser as a function of inlet conditions. Two diffusers were examined, one with 30 passages and one with 38 passages. Inlet blockage and axial asymmetry were varied over Mach numbers up to unity and over a range of inlet swirl angles. Diffuser pressure recovery and operating range were calculated using traverse measurements made upstream of the diffuser. It was found that the performance of the diffuser under different inlet conditions could be expressed to a high degree of accuracy as a single curve of non-dimensional static pressure recovery coefficient, based on availability-averaged inlet stagnation pressure, and momentum-averaged inlet flow angle. Unsteady pressure measurements showed that the diffuser entered rotating stall at reduced flow rates. No long wavelength stall precursor was determined from the measurements.

Available in PDF, EPUB and Kindle. Book excerpt: It is well known that rotating non-uniform flow pattern has a strong influence on high pressure centrifugal compressor vibrations. This paper shows the results of an experimental investigation on a typical centrifugal compressor stage running on an atmospheric pressure test rig. Unsteady flow was invariably observed at low flow well before surge. In order to determine the influence of the statoric components, the same impeller was repeatedly tested with the same vaneless diffuser, but varying return channel geometry. Experimental results show the strong effect exerted by the return channel, both on onset and on the behavior of unsteady flow.

Book excerpt: The main source of unsteadiness in the stable operating range of turbomachinery is the aerodynamical interaction of the rotor and stator rows. The blades and vanes, moving relatively to each other, interact due to viscous wakes, secondary flow phenomena as well as potential effects. As a result of this, the real flow field is highly periodically unsteady and very complex, especially in multistage engines. These effects are not yet typically addressed in current design systems of turbomachinery. It is therefore a challenge to include beneficial unsteady and secondary flow effects to improve the engine performance. This requires a detailed physical understanding of the flow field as well as the resulting influences on performance and flow stability. The present work focuses on the effects appearing in multistage axial compressors. Different aspects of blade row interactions in a four-stage low-speed compressor are discussed in comparison to the existing physical understanding. This includes experimental results on the periodical unsteady flow field within the axial gaps between the blade rows as well as the flow field within the rotor blade passages. Furthermore, the unsteady behaviour of the blade boundary layer is considered. Other discussed aspects are the influence of wakes and potential effects on the unsteady profile pressures and the excited blade pressure forces. With this work a comprehensive picture on the different features of blade row interaction is drawn."--Back cover.
