Research Project

Modeling the influence of unsteady blade interactions

The improvements in energy transformation in turbomachinery introduces higher requirements for the thermal components involved. Compared to constant-operation turbomachinery, the dynamic interactions increase in variably-operated turbomachinery. Interactions between the profile boundary layer and wake of upstream blade rows was determined to be the essential, aerodynamic interaction. A quantitative prediction and specific use of this interaction is necessary in order to enable the future design of highly efficient turbomachinery over a wide range of operating points. This requires a further development of numerical methods used in the aerodynamic design to reproduce the periodic-unsteady boundary layer transition correctly.
