摘要

Industrial turbocompressors often experience a wide range of operation. The dynamic interaction between stage components has long been recognized as an important effect that impacts both range and performance of the machine. The non-integral blade count between stationary and rotating blades has forced researchers to develop alternative numerical techniques to avoid full 360-degree sliding-mesh calculations. The relative low number of impeller blade used on a compressor, however, makes the full 360-degree simulation just as practical. This study focuses on the dynamic interaction between the inlet guide vanes and a shrouded centrifugal impeller. The primary parameter varied is the inlet guide blade count. The results between the different configurations are used to study performance implications as well as dynamic loading on the impeller itself.
