摘要： A radial turbine includes a radial turbine wheel provided with a main pathway in which blade height progressively increases while curving toward an axial direction from a radial direction. A sub-let is formed on a shroud side of the radial turbine wheel at a position separated from the main inlet in the radial direction and the axial direction. Also, a blade shape that forms the sub-inlet is such that, in a plane orthogonal to the axial line of the radial turbine wheel, a center line of the blade is inclined at a predetermined angle toward the rotation direction with respect to the radial direction.

摘要： In a centrifugal compressing apparatus, a height of a blade of an impeller is made to decrease gradually from a front edge thereof to a rear edge thereof, and a rate of change of the height of the blade is relatively large near the rear edge. The height of the blade can be made large at the rear edge side under the design restriction that an exit width of the rear edge of the blade is set to a predetermined design value. The ratio of the width of the clearance and the height of the blade is thereby made relatively large. As a result, the ratio of a flow path area occupied by a clearance flow to a flow path area occupied by a main flow is reduced. Since the pressure loss is thus made small, a drop in the efficiency can be prevented.
摘要翻译： 在离心压缩装置中，叶轮的叶片的高度从其前边缘到其后边缘逐渐减小，并且叶片的高度的变化率在后边缘附近相对较大。 在设计限制下叶片的后缘的出口宽度被设定为预定设计值的情况下，可以在后边缘侧使叶片的高度大。 因此，间隙的宽度与叶片的高度的比例相对较大。 结果，由主流所占据的间隙流量所占的流路面积与流路面积的比例降低。 由于压力损失小，所以可以防止效率下降。
