Experimental and Theoretical Characterization of the Low Frequency Acoustic Transmission through Centrifugal Pumps

By: Guidong Li,Jieyun Mao,Jorge Luis Parrondo Gayo

Fluid-dynamic noise in hydraulic systems has gained high attention in the last decades due to the increasing requirements of vibration and noise reduction in many fields. Usually the most significant sound sources in the system are fluid machines such as centrifugal pumps, in which flow pulsations are generated with amplitude that depends on the operating conditions (velocity and flow-rate). The resulting pres-sure fluctuations induced at a given frequency and position along the pipes also depend on the acoustic response of the system, i.e., on how the acoustic pulsations are transmitted or reflected at each system component, including the pump itself. Therefore, the direct meas-urement of pressure pulsations in a pipeline of a test pump does not directly reflect the acoustic properties of the pump itself, because the coupling effects of the hydraulic system, which can even cause standing waves, may be seriously misleading.

Designing Impedance Networks Converters

By: Guidong Zhang,Bo Zhang,Zhong Li

Research and application of impedance network converters are very popular in recent years, but it still lacks of understanding of and guidelines of impedance networks application, therefore, there is quiet a large potential market about impedance networks converters. This book can serve as a teaching material for graduates and guidelines for engineers as designing an impedance source converter. The main purpose of this book is to understand impedance networks of nonlinear switch circuits and impedance networks matching, which will further put forward understanding of all power converters in view of impedance networks. Taking the impedance network matchings into account leads to a set of criteria for designing an impedance source converter, which is to replace the traditional tedious, manual and experience-dependent design methods.
