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.

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.

The objective of this research has been the investigation of the nature of three-dimensional motion associated with the interaction between rotating axial flow blade rows and the working fluid, i. e. air, and the quantitative determination of the effect of three-dimensional motion upon the process of energy conversion. The investigation pertained to both the subsonic and the transonic regime of flow in turbomachines. It has been pursued by the theoretical as well as the experimental approach. Theoretical studies have been concerned with the analysis of compression shocks in regions of flow with an upstream total enthalpy gradient and with analogous patterns encountered in the flow relative to the blades of a rotating blade grid. Computations of the flow field behind threedimensional oblique shocks were carried through parallel to corresponding experimental studies.
