This book was released on 2020-12-01 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fruit de l’enseignement sur les turbomachines développé par l’auteur à l’INSA de Toulouse et à l’École des Mines d’Albi, l’ouvrage présente de façon simple et claire les machines tournantes recevant ou fournissant de l’énergie mécanique à un fluide compressible. Sont décrits et analysés les compresseurs, turbines à vapeur, turbines à gaz et turbomoteurs d’aéronefs. Conçu pour des ingénieurs et techniciens utilisateurs de ces machines, l’accent est mis sur leur constitution et leur fonctionnement. Les caractéristiques, les rendements, les avantages, les inconvénients et les conditions de choix sont précisés. De très nombreuses applications chiffrées, détaillant par le calcul les ordres de grandeur de machines industrielles sont développées sous forme d’exercices et de problèmes corrigés. L’exposé est illustré par de multiples figures (schémas, plans, photos).

Download or read book Turbomachinery written by Marco Gambini and published by Springer Nature. This book was released on 2020-09-17 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a selection of preliminary sizing procedures for turbomachinery. Applicable to both conventional and non-conventional fluids, these procedures enable users to optimize the kinematics, thermodynamics and geometry of the turbomachinery (in the preliminary design phase) using geometric correlations and losses models; to accurately predict the efficiency of turbomachinery – in most cases, in excellent agreement with CFD calculations; and to consistently analyze all turbomachines (axial and radial turbines, axial and centrifugal compressors, centrifugal pumps). The book is intended for bachelor's and master's students in industrial, mechanical and energy engineering, as well as researchers and professionals in the energy systems and turbomachinery sectors, guiding them step by step through the first sizing of turbomachines and the verification of the technological feasibility of turbomachines designed for new conversion systems operating with unconventional fluids.

This book was released on 2012-05-01 with total page 738 pages. Available in PDF, EPUB and Kindle. Book excerpt: With this second revised and extended edition, the readers have a solid source of information for designing state-of-the art turbomachinery components and systems at hand. Based on fundamental principles of turbomachinery thermo-fluid mechanics, numerous CFD based calculation methods are being developed to simulate the complex 3-dimensional, highly unsteady turbulent flow within turbine or compressor stages. The objective of this book is to present the fundamental principles of turbomachinery fluid-thermodynamic design process of turbine and compressor components, power generation and aircraft gas turbines in a unified and compact manner. The book provides senior undergraduate students, graduate students and engineers in the turbomachinery industry with a solid background of turbomachinery flow physics and performance fundamentals that are essential for understanding turbomachinery performance and flow complexes. While maintaining the unifying character of the book structure in this second revised and extended edition all chapters have undergone a rigorous update and enhancement. Accounting for the need of the turbomachinery community, three chapters have been added, that deal with computationally relevant aspects of turbomachinery design such as boundary layer transition, turbulence and boundary layer.

Download or read book Turbomachinery Performance Analysis written by R. I. Lewis and published by Butterworth-Heinemann. This book was released on 1996-05-31 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: This modern overview to performance analysis places aero- and fluid-dynamic treatments, such as cascade and meridional flow analyses, within the broader context of turbomachine performance analysis. For the first time ducted propellers are treated formally within the general family of turbomachines. It also presents a new approach to the use of dimensional analysis which links the overall requirements, such as flow and head, through velocity triangles to blade element loading and related fluid dynamics within a unifying framework linking all aspects of performance analysis for a wide range of turbomachine types. Computer methods are introduced in the main text and a key chapter on axial turbine performance analysis is complemented by the inclusion of 3 major computer programs on an accompanying disc. These enable the user to generate and modify design data through a graphic interface to assess visually the impact on predicted performance and are designed as a Computer Aided Learning Suite for student project work at the professional designer level.Based on the author's many years of teaching at degree level and extensive research experience, this book is a must for all students and professional engineers involved with turbomachinery.

Download or read book Influence des pertes thermiques sur les performances des turbomachines written by Kouadio Alphonse Diango and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans les turbomachines conventionnelles, l'estimation des performances (rendement, puissance et rapport de pression) se fait en général en admettant l'adiabaticité de l'écoulement. Mais, de nombreuses études ayant montré l'influence négative des échanges thermiques internes et externes sur les performances des petites turbomachines dans les faibles charges et aux bas régimes, cette hypothèse ne peut plus être recevable. L'objectif principal de cette thèse est de contribuer à lever l'hypothèse d'adiabaticité.Une étude préalable de l'état de l'art a permis de relever les différents types de transferts thermiques dans les turbomachines et de circonscrire notre étude.Puis, une analyse exergétique généralisée, ayant pour but la prise en compte des deux principes de la thermodynamique, a été effectuée et l'évolution de l'indice de performance caractérisant le niveau d'énergie récupérable en fonction des échanges thermiques est étudiée.Les performances des turbomachines à fluide compressible sont généralement représentées sous forme graphique dans des systèmes de coordonnées adimensionnelles établies avec l'hypothèse d'adiabaticité. Ces cartographies couramment utilisées par les exploitants et constructeurs ne conviennent pas aux machines fonctionnant avec transferts thermiques. L'étude de la similitude des turbomachines thermiques à fluide compressible présentée dans ce travail, propose de nouvelles coordonnées adimensionnelles pouvant être utilisées aussi bien en adiabatique que dans les écoulements avec transferts thermiques.Enfin, nous proposons un protocole de mesures et un modèle numérique pour l'évaluation des transferts thermiques dans un turbocompresseur.Certains résultats obtenus montrent que les performances calculées avec l'hypothèse d'adiabaticité de l'écoulement du fluide sont surestimées. Les nouvelles lois de la similitude proposées généralisent le théorème de Rateau au fluide compressible fonctionnant dans n'importe quelle condition et permettent de calculer les échanges thermiques à chaud à partir des résultats d'essai à froid. Une donnée supplémentaire (température de refoulement) est néanmoins nécessaire pour la prédiction complète des performances et des échanges thermiques.Le modèle numérique de calcul des échanges thermiques proposé donne des résultats en accord avec ceux attendus, mais nécessite des données réelles issues de mesure sur banc pour une validation complète.
