Book Synopsis Experimental Study of the Flow Field in a Model Rotor-stator Disk Cavity Using Particle Image Velocimetry by : Parag Pathak
Download or read book Experimental Study of the Flow Field in a Model Rotor-stator Disk Cavity Using Particle Image Velocimetry written by Parag Pathak and published by . This book was released on 2013 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern day gas turbine designers face the problem of hot mainstream gas ingestion into rotor-stator disk cavities. To counter this ingestion, seals are installed on the rotor and stator disk rims and purge air, bled off from the compressor, is injected into the cavities. It is desirable to reduce the supply of purge air as this decreases the net power output as well as efficiency of the gas turbine. Since the purge air influences the disk cavity flow field and effectively the amount of ingestion, the aim of this work was to study the cavity velocity field experimentally using Particle Image Velocimetry (PIV). Experiments were carried out in a model single-stage axial flow turbine set-up that featured blades as well as vanes, with purge air supplied at the hub of the rotor-stator disk cavity. Along with the rotor and stator rim seals, an inner labyrinth seal was provided which split the disk cavity into a rim cavity and an inner cavity. First, static gage pressure distribution was measured to ensure that nominally steady flow conditions had been achieved. The PIV experiments were then performed to map the velocity field on the radial-tangential plane within the rim cavity at four axial locations. Instantaneous velocity maps obtained by PIV were analyzed sector-by-sector to understand the rim cavity flow field. It was observed that the tangential velocity dominated the cavity flow at low purge air flow rate, its dominance decreasing with increase in the purge air flow rate. Radially inboard of the rim cavity, negative radial velocity near the stator surface and positive radial velocity near the rotor surface indicated the presence of a recirculation region in the cavity whose radial extent increased with increase in the purge air flow rate. Qualitative flow streamline patterns are plotted within the rim cavity for different experimental conditions by combining the PIV map information with ingestion measurements within the cavity as reported in Thiagarajan (2013).

Book Synopsis Vibration of Hydraulic Machinery by : Yulin Wu
Download or read book Vibration of Hydraulic Machinery written by Yulin Wu and published by Springer Science & Business Media. This book was released on 2014-07-08 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vibration of Hydraulic Machinery deals with the vibration problem which has significant influence on the safety and reliable operation of hydraulic machinery. It provides new achievements and the latest developments in these areas, even in the basic areas of this subject. The present book covers the fundamentals of mechanical vibration and rotordynamics as well as their main numerical models and analysis methods for the vibration prediction. The mechanical and hydraulic excitations to the vibration are analyzed, and the pressure fluctuations induced by the unsteady turbulent flow is predicted in order to obtain the unsteady loads. This book also discusses the loads, constraint conditions and the elastic and damping characters of the mechanical system, the structure dynamic analysis, the rotor dynamic analysis and the system instability of hydraulic machines, including the illustration of monitoring system for the instability and the vibration in hydraulic units. All the problems are necessary for vibration prediction of hydraulic machinery.
Book Synopsis Rotor-Stator Interaction in Radial Turbomachines by : Giovanna Cavazzini
Download or read book Rotor-Stator Interaction in Radial Turbomachines written by Giovanna Cavazzini and published by LAP Lambert Academic Publishing. This book was released on 2013-01 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction between rotating and stationary parts affects the flow field inside both components, modifying the machine performance in terms of operating stability, structural vibrations, noise and pressure pulsations. The aim of this book is to improve the understanding of the rotor-stator interaction phenomena with an extensive in-depth investigation of their characteristics, origin, development and effects on the machine performance. An unusual acoustical approach, aimed at identifying a possible connection between noise emissions and inner fluid-dynamics, was proposed and combined with a PIV experimental analysis in order to study the unsteady flow phenomena developing inside the pump vaned diffuser. These analysis, coupled with a numerical analysis on the same turbomachine, allowed to analyze in-depth the effects of the rotor-stator interaction on the machine flow field and hence on its performance.
Book Synopsis Hydrodynamics of Pumps by : Christopher E. Brennen
Download or read book Hydrodynamics of Pumps written by Christopher E. Brennen and published by Cambridge University Press. This book was released on 2011-03-28 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrodynamics of Pumps is a reference for pump experts and a textbook for advanced students. It examines the fluid dynamics of liquid turbomachines, particularly pumps, focusing on special problems and design issues associated with the flow of liquid through a rotating machine. There are two characteristics of a liquid that lead to problems and cause a significantly different set of concerns than those in gas turbines. These are the potential for cavitation and the high density of liquids, which enhances the possibility of damaging, unsteady flows and forces. The book begins with an introduction to the subject, including cavitation, unsteady flows and turbomachinery, basic pump design and performance principles. Chapter topics include flow features, cavitation parameters and inception, bubble dynamics, cavitation effects on pump performance, and unsteady flows and vibration in pumps - discussed in the three final chapters. The book is richly illustrated and includes many practical examples.
