Abstract: In this work, the impact of the airfoil shape on flutter is investigated. Flutter occurs when the blade structure is absorbing energy from its surrounding fluid leading to hazardous amplification of vibrations. The key for ...

Abstract: This paper presents experimental investigations on flat plate filmcooling in combination with a ribbed cooling channel. The effect of rib placement on the filmcooling injection and the flow in the cooling channel was ...

Abstract: An important aspect of the aerodynamic flow field in the tip region of axial compressor rotors is the unsteady interaction between the tip clearance vortex (TCV) and the incoming stator wakes. In order to gain an improved ...

Abstract: Proportionally large relative radial clearances can be found within the rear stages of multistage axial compressors of gas turbines and aero engines, with significant impact on their efficiency. A new threedimensional ...

Abstract: This paper will compare two approaches of sensitivity analysis, namely (i) the adjoint method which is used to obtain an initial estimate of the geometric sensitivity of the gas-washed surfaces to aerodynamic quantities ...

Abstract: This paper reports endwall filmcooling investigations with single and multiple rows of fanshaped film holes using temperaturesensitive paint (TSP). The experiments are carried out in a sixbladed linear cascade based on the ...

Abstract: Film cooling and internal passage cooling play a fundamental role in turbine blade cooling. As the cooling holes are fed by the internal crossflow, interaction of these both cooling strategies is implicated. The influence ...
