Abstract: The aerodynamic performance of a Savonius rotor has been studied by measuring the pressure distributions on the blade surfaces at various rotor angles and tip-speed ratios. It is found that ...

Abstract: In this study, a method is developed for predicting the future deformation of soft ground, based on measured data. Because it is difficult to predict the deformation behavior of soft ground on the basis of laboratory ...

Abstract: This paper describes in detailed flow field in a centrifugal compressor with a vaned diffuser at off design point. Especially, we conducted both the experimental and numerical analysis in order to investigate the evolution ...

Abstract: This paper presents a method of determining the locations of unbalances on a rotor when the unbalances occur abruptly during rotor running. The method makes use of journal vibrations, because, ...

Abstract: Unsteady pre-stall behavior in a centrifugal compressor with a vaned diffuser was investigated by experimental and numerical analysis. The pre-stall disturbances occurred at a slightly higher flow coefficient at the stall ...

Abstract: The impeller stall inception in a high-pressure ratio centrifugal compressor with bleed slots was investigated by experiments and unsteady numerical analysis. This study reported that the flow instability of the internal ...

Abstract: The unsteady flow structure of the rotating instability (RI) in a 1.5-stage axial compressor is investigated through experimental and numerical analyses. In the tested compressor, the total pressure rise of the rotor ...
