Abstract: The blade mode shape and acoustic properties are important factors that affect the aeroelasticity of fan blades. The goal of this paper is to investigate the stall flutter mechanism associated with the first mode and its ...

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: Tip clearance is a critical parameter affecting fan performance and aeroelastic stability. This paper investigates the effect of tip clearance on fan aeroelasticity under different acoustic propagation characteristics ...

Abstract: Abstract. The tip clearance flow, closely related to stable margin and efficiency, influences the performance of the fan/compressor in aeroengines. The unsteady tip flow in a high-speed transonic fan rotor is studied by ...

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: The coupling effect between the complex vortex system and the rim purge flow in the endwall region of a high-lift low-pressure turbine (LPT) will significantly influence the evolution of secondary flow and the corresponding ...

Abstract: Tip clearance is a critical parameter affecting fan performance and aeroelastic stability. This paper investigates the effect of tip clearance on fan aeroelasticity under different acoustic propagation characteristics ...

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: Abstract. The supersonic through-flow variable-pitch tandem cascade has a significant potential for widening the acceptable inflow range of fans, but its internal flow mechanisms are not yet fully understood. This study ...

Abstract: This paper presents an experimental investigation of the flow mechanisms in an aggressive interturbine transition duct with and without lowprofile vortex generators flow control. The interturbine duct had an area ratio of ...
