The computed flow angles at the inlet and exit of the rotor agreed well with the experimental results in the scale-model turbine and also with the results based on the quasi 3-D inviscid flow analysis. It is clearly shown that the spiral-type vortex appears due to the reverse flow at the rotor root, and in addition, the leading-edge separation occurs on the pressure surface over the rotor blade height, especially a large separation occurs at the root side due to a high incidence angle. The present study suggests that the unstable flow might be caused by the spiral-type vortex and the leading-edge separation under lower load operations.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"日本機械学會論文集.
