Abstract: In this study, the flutter mechanism related to acoustic propagation characteristics of a wide-chord fan rotor was investigated numerically. The first bending mode and its two and three nodal diameters traveling wave ...

Abstract: This paper describes the stall mechanism in an ultrahigh-pressure-ratio centrifugal compressor, composed of a double-splitter impeller, radial diffuser, and axial diffuser. A model comprising all impeller and diffuser blade ...

Abstract: This research presents a series of simulations that investigate the effects of tip clearance on the aeroelastic stability of a wide-chord high-speed transonic fan rotor. The results show that the stall margin and the total ...

Abstract: In this study, molten-salt electrolysis of silica was investigated to identify the role played by electrolytic conditions on the deoxidization depth. Four key conditions that included particle size, electrolytic temperature, ...

Abstract: The development of highly active and stable electrocatalysts is a major challenge for water electrolysis. In this work, we designed bimetallic nitrogen-doped carbon (NiCo-NC) materials with excellent performance, which ...
