Vibration Analysis of Blade Under Multiple Composite Unsteady Excitations
In order to understand the effects of the unsteady aerodynamic excitations in complex flow field on blades, on the basis of the data obtained from the single-stage axial flow compressor, three kinds of exciting forms in the compressor had been studied, including the correlation between excitations and responses in the upstream blade row wake, inlet distortion and rotating stall. Results showed ...
متن کاملEffect of Reduced Frequency on the Unsteady Aerodynamic Performance of a Wind Turbine Blade Section
The blades of wind turbines are the most important parts in producing power output. In this study, a section of a 660 KW wind turbine blade will be installed in Iran in near future was tested in a wind tunnel. In addition to steady tests, various unsteady tests including the effects of reduced frequency, mean angle of attack, and amplitudes were carried out. The preliminary results show strong ...

متن کاملPrediction of unsteady loading on a steam turbine blade
A single rotor CFD model using wall-modeled Large Eddy Simulations (LES) was performed to predict the unsteady loading on the blade surface under partial admission. Geometry of the rotor blade of high pressure steam turbine of a 500 MW fossil-fuel power plant was used for this study. Periodically changing inlet boundary model was developed for single rotor model to simplify a full annular of th...
متن کاملUnsteady Lift Slope Values Obtained from Flight Measurements in Gusts
SUINARY Flight measurements have been made of the unsteady lift due to gusts on a Meteor 7 aircraft. Values of the lift slope obtained from these measurements show a marked reduotion with increasing frequency, and in the range 1 to 5 cIp.a~, da(f) df =-0.2 per oppose; at 5 c.p.s. the value of the lift slope is reduced to three quarters of its steady state value, The main experimental errors inh...
