This work presents a comparison study of the CFD modeling with two different turbulence approaches viz. unsteady RANS and LES, on full-scale model (New) MEXICO rotor wind turbine. The main emphasis paper is wake aerodynamics. Simulations are carried out for three speeds considered in experiment (10, 15, 24 ms−1). results uRANS LES compared against experimental measurements pressure distribution...

Fouling is the most important performance degradation factor, so it is necessary to accurately predict the effect of fouling on engine performance. In the previous research, it is very difficult to accurately model the fouled axial flow compressor. This paper develops a new performance calculation method of fouled multistage axial flow compressor based on experiment result and operating data. F...

An experimental study was conducted to investigate on the effects of the relative rotation directions of two tandwm wind turbines on the power production performance and flow characteristics in the wakes of two wind turbines in tandem. The experimental study was performed in a large-scale Aerodynamics/tmospheric Boundary Layer (AABL) Wind Tunnel located at the Aerospace Engineering Department o...

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 ...
