The paper deals with evaluation of experimental data obtained from the real-size 30 MW output Waste to Energy steam turbine. For many turbine regimes pressures in last stage area were obtained. At same time amplitudes blade tips vibrations measured rotor blades using tip timing system and axial velocity at outlet. are mutually correlated relations analysed between increased vibration values pre...

The Axial compressor is an integrated part of a gas turbine. The central part of compressors is its blades. Blade aerodynamic has a significant effect on compressor performance. Because of the adverse pressure gradient in the compressor, any deviation in the blade profile has a significant influence on the flow field as well as the compressor performance. During the manufacturing and operation ...

(2006) Laser-optical investigation of stator-rotor interaction in a transonic turbine, 1 ABSTRACT This paper presents research in a highly-loaded cold-flow transonic turbine under continuous and engine like conditions. Special focus was placed on blade row interaction at app. 10600 rpm. While the first step was the investigation of a single stage machine (stator-rotor), the second step extended...

A compact sized PDE with an i.d. of 0.75 in. and length of 1 m was paired with an automotive turbocharger. The turbine-compressor shaft was used to drive a small ac generator by means of speed reduction wheels. The PDE was tested with propane-oxygen mixture at 15 Hz for a period of about 20 s. The turbine spun up to a speed of 127,000 rpm, whilst the generator produced electric power at 27 W an...

The transport of entropy waves and their impact on the stage aerodynamics are still open questions. This paper shows results an experimental campaign that focuses swirling advection through axial turbine stator. research aims at quantifying aerodynamic first nozzle characterizing transport. disturbance is generated by a novel wave generator ensures wide set different injection parameters. devic...
