... of the blading. With the unsteady flow analysis by means of HWA a typical spectrum of the axial velocity component was found which is shown in Fig. 5 . A dominating frequency of 13 Hz appears around midspan of the blades (Fig. 5a ). This peak is increasingly damped inside the boundary layer until...

... unsteady. The unsteady flow interactions between the turbine and the exhaust system have a strong impact on the blade loading or blade aerodynamic force. This paper describes the unsteady flow interactions between a single-stage axial turbine and an exhaust system. The experimental and numerical studies...

.... This allows the exhaust pulses originating from the internal combustion exhaust to be preserved. Since the turbine is fed by two separate unsteady flows, the phase difference between the exhaust pulses entering the turbine rotor will produce a momentary imbalance in the flow conditions around the periphery...
