This book was released on 2014 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential performance benefit of actuating inlet guide vane (IGV) angle, variable diffuser vane (VDV) angle and impeller speed to implement a multi-parameter control on a centrifugal compressor system is assessed. The assessment consists of first developing a one-dimensional meanline model for estimating performance of centrifugal compressor system followed by the formulation of a control framework incorporating the meanline model. Performance estimate of a representative centrifugal compressor system with adjustable IGV angle, VDV angle and impeller speed using the meanline model is in accord with available test data. The impeller performance estimate based on the meanline model is also in accord with computed results from Reynolds Average Navier-Stokes Equations. The simple control framework can be used to optimize on the fly the compressor operation to meet a specific mission requirement by selecting an appropriate combination of impeller speed, IGV and VDV angle settings. Desirable flow configurations with the required performance in response to specified operating needs have been obtained to serve as illustrations on the practical utility of the control framework. Results provide guidelines and attributes of compressor for achieving the required performance and operation at the system level through prioritizing the actuation of the adjustable parameters; for instance impeller speed would provide a high level of leverage to affect the compressor performance on an effective basis and that the IGV angle should be confined to a specified range. While the results have not been assessed in an experimental setting, they are used to design and plan an experimental program for evaluating the proposed simple multi-parameter control strategy. Flexibility have been incorporated into the formulation to allow the refinement and updating of the model for improved accuracy and fidelity.

Available in PDF, EPUB and Kindle. Book excerpt: The latest update to Bela Liptak's acclaimed "bible" of instrument engineering is now available. Retaining the format that made the previous editions bestsellers in their own right, the fourth edition of Process Control and Optimization continues the tradition of providing quick and easy access to highly practical information. The authors are practicing engineers, not theoretical people from academia, and their from-the-trenches advice has been repeatedly tested in real-life applications. Expanded coverage includes descriptions of overseas manufacturer's products and concepts, model-based optimization in control theory, new major inventions and innovations in control valves, and a full chapter devoted to safety. With more than 2000 graphs, figures, and tables, this all-inclusive encyclopedic volume replaces an entire library with one authoritative reference. The fourth edition brings the content of the previous editions completely up to date, incorporates the developments of the last decade, and broadens the horizons of the work from an American to a global perspective. Béla G. Lipták speaks on Post-Oil Energy Technology on the AT&T Tech Channel.
Download or read book Predicting Stage Performance of a Multi stage Centrifugal Compressor Using the Overall Compressor Performance Characteristic written by Dirk Cornelius Human and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The reliable operation of Integrally Geared Centrifugal Compressors (IGCCs), used in the coal-fired power generation industry of South Africa, is essential for economic, environmental and safety considerations. However, due to the unavailability of individual stage performance curves, the ability of a compressor owner to identify underperforming stages to maintain these compressors proactively remains limited. This study addresses the stage performance prediction of an IGCC when only the compressor's overall performance characteristic, in conjunction with the impeller diameters and tip speeds, are known. The study is limited to IGCCs used in the coal-fired power generation industry of South Africa. Based on the limited inputs, two performance modelling methods were considered for this application, namely stage stacking and 1-dimensional modelling. However, stage stacking requires known operating points on each stage performance curve from which the rest of the curve can be extrapolated while 1-dimensional models require detailed stage design information to model stage performance. This study developed a revised stage stacking procedure which in contrast to the traditional stage stacking procedure, does not require a known operating point on each stage's performance curve, for it assesses the relative stage performance at the compressor's surge flow rate. The relative maximum pressure ratio of each stage is acquired through the application of similarity principles while a simplified 1-dimensional impeller analysis model is used to assess relative impeller head coefficients. The modelling process was developed based on performance and design data for IGCCs obtained from a compressor manufacturer. Performance data of four IGCCs, consisting of 13 stages, were obtained, including the design data for ten impellers. Hence, the IGCCs satisfy the requirements of geometric and aerodynamic similarity, unveiling a linear relationship between the stage impeller tip speed and maximum pressure ratio. A simplified 1-dimensional performance model was used to assess relative impeller head coefficients. A verification procedure ensured the integrity of the findings of the 1-dimensional model was maintained by comparing the model results to findings obtained using commercial compressor performance modelling software. A sensitivity analysis was conducted on the 1-dimensional performance model to ascertain which input parameters could be scaled as a function of the impeller tip diameter. For the four IGCCs for which data were obtained, the stage-discharge pressure and isentropic efficiency curves were calculated using the developed model. The maximum variation between the measured and calculated pressure and isentropic efficiency curves equaled 8.20% and 10.84%, respectively. The prediction accuracy of the developed modelling procedure is similar to map-based models found in literature and is considered adequate for identifying an underperforming stage. Thus, the developed model could serve as a valuable conditioning monitoring tool for site-based compressor owners.

Available in PDF, EPUB and Kindle. Book excerpt: A mechanical engineer with a Pennsylvania turbomachinery company, A ungier describes his own system and strategy for designing and analyzing centrifugal compressor aerodynamics. To address the novice as well as the experienced in the field, he presents the basic thermodynamic and fluid dynamic principles, empirical models, and key numerical methods that form the basis of his methods. His strategy, or design practice, he found harder to describe because it involves a process of reasoning rather than following an established set of principles. He recognizes that his is only one of many possible methods, but makes no effort to compare or contrast his with any other.
