Simulation of tail boom vibrations using main rotor-fuselage Computational Fluid Dynamics (CFD) [PDF]

, 2017
In this work, fully-resolved rotor-fuselage interactional aerodynamics is used as the forcing term in a model based on the Euler-Bernoulli equation, aiming to simulate helicopter tail-boom vibration.

Numerical analysis of transonic flow over the FFA-W3-211 wind turbine tip airfoil [PDF]

Wind Energy Science
Modern wind turbines are the largest rotating machines ever built, with blade lengths exceeding 100 m. Previous studies demonstrated how the flow around the tip airfoils of such large machines reaches local flow Mach numbers (Ma), at which the ...

Numerical simulation of the fluid–structure interaction in a tube array under cross flow at moderate and high Reynolds number [PDF]

, 2014
The unsteady loads in a tube bundle are studied at moderate and high Reynolds number by means of URANS and hybrid (DDES) modelling. The onset of fluid-elastic instability is analysed for different structural parameters, Scruton number and reduced ...

Study of Convective Flow Effects in Endwall Casing Treatments in Transonic Compressor Rotors [PDF]

, 2012
The unsteady convective flow effects in a transonic compressor rotor with a circumferential-groove casing treatment are investigated in this paper. Experimental results show that the circumferential-groove casing treatment increases the compressor stall ...
