Abstract

Many opportunities exist in industry to improve efficiency thereby reducing energy consumption and cost. The wave rotor is a device which manipulates expansion and shockwaves to compress gases with theoretically high efficiency, unrivalled by other known means. Applications vary from refrigeration to internal combustion engine superchar-ging. Although research has been carried out for many decades, it is very much a work in progress technology. To improve the understanding of performance, analysis and design of wave rotors used for air pumping applications. Experimental testing, computational fluid dynamics (CFD) simulations and the development of a one-dimensional (1D) math-ematical analysis method has been performed in the present work. The 1D analysis method developed provides a low computational cost alternative to CFD for preliminary design with exceptional correlation to experimental results published in literature. As part of this work a pressure exchanger equalising wave rotor (PEEWR) was experimentally tested to expand on experimental performance maps published in literature. The same trends in performance were successfully reproduced, however the overall performance was substantially lower than published data for other devices. Causes for the low exper-imental performance was investigated using CFD. It was identified that viscous effects and suboptimal porting were the main contributors to the low experimental performance. With improved design using the tools and techniques developed and demonstrated in this work it is expected that wave rotor performance matching that demonstrated elsewhere can be achieved. This will enable future research, development and deployment of wave rotor concepts for application in industrial energy efficiency initiatives.
