Developments in Turbomachinery Flow Excerpt :

Developments in Turbomachinery Flow: Forward Curved Centrifugal Fans explores the forward curved squirrel cage fan as an excellent instrument for fluid mechanics research in turbomachines. The book explores phenomena such as jet/wake interaction, circulation, separation and noise in turbomachines, also addressing the characteristics that are specific to this fan and applications in other centrifugal turbomachines. Chapters begin with a general introduction that includes research techniques and a survey of older research, and then proceed into a detailed description of improvements for different parts of the fan, including the inlet, the rotor and the volute. Final sections include a comprehensive discussion on geometrical modifications that could improve performance without impacting cost. Explores how forward curved centrifugal fans have wide industrial application Discusses the strong trade-off between fan aerodynamics and construction cost Provides a wide selection of optimums for geometrical configuration Introduces new geometries that can improve performance and reduce noise for the same construction cost Presents fluid phenomena as a potential research field for this fan

Developments in Turbomachinery Flow Excerpt :

Turbomachines are used in a wide range of applications - petrochemical industries, power engineering, ventilations, and many other fields. Increasing the efficiency and operating range of turbomachines reduces fuel consumption of gas turbine power plants and other applications. Over the years, many attempts have been made to achieve these objectives. The demand for high performance turbomachinery and related new applications is always the motivation for the development in analyzing the complicated internal flows, reducing noise emission level, and altering or controlling the characteristics. In recent years, much progress has been made with regard to advanced optimization algorithms, gas-solid or gas-liquid complex flows, and new types of turbomachinery.Developments in Turbomachinery Flow focuses on the current and future science and technology development of turbomachinery in the related fields of turbomachinery based propulsion and power systems. Of primary interest are the thermodynamics, the fluid mechanics, the heat transfer and the applied combustion of aerospace, marine and industrial energy devices and systems, both from a component and system perspective. The contributed chapters are written by renowned authors, researchers, and scientists that will stimulate efforts to optimize the aerodynamic design via new models or algorithms, to address the challenges inherent in turbomachinery by developing new theories or proposing new engineering concepts, and to minimize the energy losses by using active or passive control approaches. Advanced methods and practical applications for energy-saving and emission reduction in the industry are also addressed.This book is intended to offer to students and practitioners with a primary interest in turbomachinery. Designers, manufacturers and researchers in the area of ventilation systems and power plants will also find this book as valuable guide.

Advances of CFD in Fluid Machinery Design Excerpt :

In the past Computational Fluid Dynamics (CFD) was confined to large organisations capable of developing and supporting their own codes. But recently there has been a rapid increase in the availability of reasonably priced commercial codes, and many more industrial organisations are now able to routinely use CFD. Advances of CFD in Fluid Machinery Design provide the perfect opportunity to find out what industry is doing and this book addresses how CFD is now being increasingly used in the design process, rather than as a post-design analysis tool. COMPLETE CONTENTS Trends in industrial use of CFD Challenges and methodologies in the design of axial flow fans for high-bypass-ratio, gas turbine engines using steady and unsteady CFD A three-dimensional inverse method based on pressure loading for the design of turbomachinery blades Application of CFD to the design and analysis of axial and centrifugal fans and compressors The design and performance of a transonic flow deswirling system – an application of current CFD design techniques tested against model and full-scale experiments Recent developments in unsteady flow modelling for turbomachinery aeroelasticity Computational investigation of flow in casing treatments for stall delay in axial flow fans Use of CFD for the three-dimensional hydrodynamic design of vertical diffuser pumps Recommendations to designers for CFD pump impeller and diffuser simulations Three dimensional CFD – a possibility to analyse piston pump flow dynamics CFD analysis of screw compressor performance Prediction of aerothermal phenomena in high-speed discstator systems Use of CFD in the design of a shaft seal for high-performance turbomachinery Users and potential users, of CFD for the design of fluid machinery, managers, designers, and researchers working in the field of ‘industrial flows’, will all find Advances of CFD in Fluid Machinery Design a valuable volume discussing state-of-the-art developments in CFD.

Turbomachinery Performance Analysis 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.

Engineering Turbulence Modelling and Experiments 5 Excerpt :

Turbulence is one of the key issues in tackling engineering flow problems. As powerful computers and accurate numerical methods are now available for solving the flow equations, and since engineering applications nearly always involve turbulence effects, the reliability of CFD analysis depends increasingly on the performance of the turbulence models. This series of symposia provides a forum for presenting and discussing new developments in the area of turbulence modelling and measurements, with particular emphasis on engineering-related problems. The papers in this set of proceedings were presented at the 5th International Symposium on Engineering Turbulence Modelling and Measurements in September 2002. They look at a variety of areas, including: Turbulence modelling; Direct and large-eddy simulations; Applications of turbulence models; Experimental studies; Transition; Turbulence control; Aerodynamic flow; Aero-acoustics; Turbomachinery flows; Heat transfer; Combustion systems; Two-phase flows. These papers are preceded by a section containing 6 invited papers covering various aspects of turbulence modelling and simulation as well as their practical application, combustion modelling and particle-image velocimetry.
