Unsteady Flows and Forces by Turbine Rotor-Stator Interactions

抄録

With the urgent demand for higher performance in axial turbines, the unsteadiness induced by the mutual interactions between the nozzle and rotor cascade rows has attracted much attention. As the number of published papers on this topic has recently increased considerably, the present state of research is reviewed here under four categories. This report might be expected to deepen our understanding of the unsteadiness within the turbine stages and also to provide some suggestions for further research in this field.
