Abstract: Abstract. Aeroelastic simulations of turbomachinery involve complex fluid–structure interaction analyses, which require solving three problems simultaneously: the fluid problem, the structural problem, and the mesh motion ...

Abstract: The effect of the operating conditions on the vibration amplitude trends of an isolated low-pressure turbine rotor is described. The study utilizes an analytical model correlating the aerodynamic and dry-friction work ...

Abstract: Abstract. In the forcing of a low-pressure turbine (LPT) bladed disk, the final amplitude of the vibration state that sets in is determined by the dissipation produced by the friction forces at the blade-disk contact ...

Abstract: This paper presents a methodology to estimate the vibration amplitude of fluttering low-pressure turbine (LPT) blades saturated due to friction effects. The study utilizes an analytical model that balances aerodynamic work ...

Abstract: Abstract. Flutter design criteria in aeronautical fans and cantilever low-pressure turbines (LPTs) differ significantly. Modern LPT blades often exhibit aeroelastic instability across multiple nodal diameters but are ...

Abstract: This paper aims to establish an efficient and accurate computational fluid dynamic (CFD) method for calculating the flutter stability of fan blades in the presence of inlet distortion due to crosswind. Due to the asymmetry ...

Abstract: In this paper, a new aeroelastic phenomena for fans, referred to as non-synchronous forced vibration (NSFV), is presented. This type of aeroelastic instability can occur at high crosswind conditions when the flow at the ...
