This book describes the analysis and behaviour of internal flows encountered in propulsion systems, fluid machinery (compressors, turbines and pumps) and ducts (diffusers, nozzles and combustion chambers). The focus is on phenomena that are important in setting the performance of a broad range of fluid devices. The authors show that even for complex processes one can learn a great deal about the behaviour of such devices from a clear understanding and rigorous use of basic principles. Throughout the book they illustrate theoretical principles by reference to technological applications. The strong emphasis on fundamentals, however, means that the ideas presented can be applied beyond internal flow to other types of fluid motion. The book equips students and practising engineers with a range of new analytical tools. These tools offer enhanced interpretation and application of both experimental measurements and the computational procedures that characterize modern fluids engineering.

This physics-first, design-oriented textbook explains concepts of gas turbine secondary flows, reduced-order modeling methods, and 3-D CFD.

Numerical Computation of Internal and External Flows Volume 1: Fundamentals of Numerical Discretization C. Hirsch, Vrije Universiteit Brussel, Brussels, Belgium This is the first of two volumes which together describe comprehensively the theory and practice of the numerical computation of internal and external flows. In this volume, the author explains the use of basic computational methods to solve problems in fluid dynamics, comparing these methods so that the reader can see which would be the most appropriate to use for a particular problem. The book is divided into four parts. In the first part, mathematical models are introduced. In the second part, the various numerical methods are described, while in the third and fourth parts the workings of these methods are investigated in some detail. Volume 2 will be concerned with the applications of numerical methods to flow problems, and together the two volumes will provide an excellent reference for practitioners and researchers working in computational fluid mechanics and dynamics.

A practical, illustrated guide to thermal science A practical, illustrated guide to thermal science Written by a subject-matter expert with many years of academic and industrial experience, Thermal Science provides detailed yet concise coverage of thermodynamics, fluid mechanics, and heat transfer. The laws of thermodynamics are discussed with emphasis on their real-world applications. This comprehensive resource clearly presents the flow-governing equations of fluid mechanics, including those of mass, linear momentum, and energy conservation. Flow behavior through turbomachinery components is also addressed. The three modes of heat transfer--conduction, convection, and radiation--are described along with practical applications of each. Thermal Science covers: Properties of pure substances and ideal gases First and second laws of thermodynamics Energy conversion by cycles Power-absorbing cycles Gas power cycles Flow-governing equations External and internal flow structures Rotating machinery fluid mechanics Variable-geometry turbomachinery stages Prandtl-Meyer flow Internal flow, friction, and pressure drop Fanno flow process for a viscous flow field Rayleigh flow Heat conduction and convection Heat exchangers Transfer by radiation Instructor material available for download from companion website

Static tests of an annular conical-shock inlet and an open-nose conical inlet with three lip shapes were conducted at the Langley 8-foot transonic tunnel. Measurements of pressure recovery, surface pressure, and total pressure were made through a mass-flow range extending to choking. The results indicate that the two inlets with thin sharp lips had about the same relatively poor pressure-recovery characteristics and choked at a mass-flow rate of about 78 percent of the theoretical maximum. However, both the pressure recovery and choking mass-flow rate were greatly improved by replacing the sharp lip by two alternate shapes with lip roundness and internal contraction just behind the inlet lip.
