Book Description
The flow of an incompressible inviscid fluid through a turbomachine with blade rows consisting of an infinite number of similar infinitely thin blades has been investigated theoretically in order to examine and describe the three-dimensional flow phenomena and to illustrate the methods of calculation developed.

Book Description
A relatively simple, rapid method for predicting the three-dimensional flow effects in turbomachinery of arbitrary configuration was investigated. Although the two-dimensional cascade is a satisfactory approximation for the design and analysis of some types of turbomachines, the flow through devices such as propeller pumps, inducers, and fans for turbofan engines may deviate significantly. No solution exists for the complete, unified three-dimensional flow problem, but analyses which include the effect of three-dimensional flows have been developed. These typically involve lengthy numerical solutions for specialized cases and are not optimum for design nor for a unified study of three-dimensional flow trends.

Book Description
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.

Book Description
Worked Examples in Turbomachinery (Fluid Mechanics and Thermodynamics) is a publication designed to supplement the materials in Fluid Mechanics, Thermodynamics of Turbomachinery, Second Edition. The title provides detailed solution for the unanswered problems from the main textbook. The text first covers dimensional analysis, and then proceeds to tackling thermodynamics. Next, the selection discusses two-dimensional cascades. The text also talks about axial flow turbines and compressors, along with the three-dimensional flow in axial turbo machines. Chapter 7 covers centrifugal compressor and pumps, while Chapter 8 tackles radial flow turbines. The book will be of great use to students of mechanical engineering, particularly those who have access to the main textbook.

Book Description
The primary objective of this two-year research project is to develop a finite-difference numerical technique for the solution of the parabolized Navier-Stokes equations using a system of surface-oriented coordinates suitable for ducts of arbitrary geometry. An additional objective to be fulfilled by this research consists of developing an analysis for laminar duct flow with stream wise separation using mathematical models simpler than the full Navier-Stokes equations. In order to achieve the above objectives, the following three problems have been studied during the first year of the two-year contract period: I. Laminar Flow through Joukowski ducts, II. Laminar flow through curved polar ducts, and III. Analysis of laminar streamwise flow separation via a semi-elliptic mathematical model. In each phase of the research attention is given to the accuracy of the numerical solutions as well as the efficiency with which they can be determined. For this purpose, the following two additonal areas have been studied: iv. Higher accuracy of numerical solutions, and v. Efficient numerical algorithms. Suitable model problems have been selected wherever required, in this research, with the overall goal of contributing to further the understanding of internal flows in turbomachinery. Each of the above research areas is described in this report. (Author).
