Kurzbeschreibung
Although some books have been published in this field, there is no an advanced book focusing on turbomachinery aerothermodynamics with systematic introduction of fundamental theory, experimental methods, industrial applications and the latest developments. With his over 50 years' experience in the area, Chen's book fills the gap. The book focuses on four aspects: direct and inverse solutions, flow phenomena, and design optimization.

Computational Fluid Dynamics (CFD) is now an essential and effective tool used in the design of all types of turbomachine, and this topic constitutes the main theme of this book. With over 50 years of experience in the field of aerodynamics, Professor Naixing Chen has developed a wide range of numerical methods covering almost the entire spectrum of turbomachinery applications. Moreover, he has also made significant contributions to practical experiments and real-life designs.
The book focuses on rigorous mathematical derivation of the equations governing flow and detailed descriptions of the numerical methods used to solve the equations. Numerous applications of the methods to different types of turbomachine are given and, in many cases, the numerical results are compared to experimental measurements. These comparisons illustrate the strengths and weaknesses of the methods - a useful guide for readers. Lessons for the design of improved blading are also indicated after many applications.
* Presents real-world perspective to the past, present and future concern in turbomachinery
* Covers direct and inverse solutions with theoretical and practical aspects
* Demonstrates huge application background in China
* Supplementary instructional materials are available on the companion website
